In CISK, surface convergence (pink horizontal arrows) causes rising motion around a surface cyclone(labeled as L). The air cools as it rises (red vertical arrows) and condensation occurs, which release Are the surface winds in a cyclone converging or diverging? Converging. Is the air in the center of the cyclone subsiding or rising? What effect will this have on the potential for condensation and precipitation

The upper level divergence will cause the surface pressure at the center of the hurricane to decrease. The speed of the converging surface winds increases and the storm intensifies. The converging winds pick up additional heat and moisture which warms the core of the hurricane even more •Converging, cyclonic air motion at surface •Surface winds are strongest in eyewall •Diverging, anticyclonic motion at tropopause level •Rising motion occurs in the eyewall •Subsidence on outer edge of storm rain bands •Sinking motion in the ey 1. Surface winds in a cyclone are converging. Because, there is low pressure zone in a center of cyclone at the surface and a high pressure zone aloft. So surface winds converge towards low pressure center and diverge aloft Anticyclones are associated with high pressure, clockwise circulation and winds spiral outward. A low, or cyclone, has converging surface winds and rising air, resulting in cloudy conditions and often precipitation. A high, or anticyclone, has diverging surface winds and descending air, which leads to clear skies and fair weather converging winds aloft 048. Weather in midlatitude cyclones tends to be cloudy and wet because of the ___ surface winds and ___ ai

The convergence of horizontal winds causes air to rise, whereas the divergence of horizontal winds causes downward motion of the air (subsidence). Ground-level atmospheric pressure is not affected by convergence if divergence of an equal magnitude occurs simultaneously at higher levels Air rises in low pressure systems because of the convergence of air at the surface and diverging air aloft which forms clouds. For the cyclone to intensify, the diverging air aloft has to be greater than the converging air at the surface. This essentially pulls more air upwards and the surface pressure of the system drops, intensifying the cyclone As already described, a cyclone is a wind pattern circulating a low-pressure system, counterclockwise in the Northern Hemisphere & clockwise in the Southern Hemisphere. Most cyclones (and all their variations) form over the warm waters of the Tropics. As the warm, humid air starts to rise, it leaves an area of low pressure close to the surface Divergent winds are winds that are moving away from something. Convergent winds are winds that are moving towards something In order for convergence to take place, the winds must be such as to result in a net inflow of air into a layer or region. At the surface, low-pressure systems are associated with con-vergent flow. The winds cross isobars toward the center of the low and push the air in the center upward into the atmosphere

Which of the following best explains why cyclones tend to dissipate on the windward side of mountain ranges (c) Tropical Cyclones. Tropical cyclones form when disturbances move over warm water and intensify because of the effects described above. However, tropical cyclones intensifying through all the stages to eventually become hurricanes are much more intense than can be anticipated by a consideration of the sea surface temperature patterns alone The convergence due to stronger wind moving into weaker wind replenishes the mass lost due to the divergence in the diffluent flow. In the bottom diagram below, notice in the diffluent pattern that strong wind is moving into weaker wind and the air streams are diverging over distance also The term cyclone is a revolving weather system in which air spirals in at the base and rises, creating a low pressure area at ground level.

When reading a surface weather chart, centers of highs and lows are represented by pressure lines called. a. isotherms The anticyclonic pattern can be visualized as upper air sinking down into the center of the high and then diverging near the ground surface. Opposite conditions prevail in a low-pressure center, with the air converging horizontally into the cyclone and then rising Cyclone. An area of closed pressure circulation with rotating and converging winds, the center of which is a relative pressure minimum. The circulation is counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere. Also called a low pressure system and the term used for a tropical cyclone in the Indian Ocean Few things in nature can compare to the destructive force of a hurricane. Called the greatest storm on Earth, a hurricane is capable of annihilating coastal areas with sustained winds of 155 mph or higher and intense areas of rainfall and a storm surge. In fact, during its life cycle a hurricane can expend as much energy as 10,000 nuclear bombs

Average sea level pressure is __________. 7.4 kilograms per sq. cm. 7.4 pounds per sq. in. 14.7 kilograms per sq. cm The Intertropical Convergence Zone (ITCZ, pronounced itch), known by sailors as the doldrums or the calms because of its monotonous windless weather, is the area where the northeast and the southeast trade winds converge. It encircles Earth near the thermal equator though its specific position varies seasonally. When it lies near the geographic Equator, it is called the near-equatorial trough The surface winds are cyclonic (counterclockwise) and toward the low pressure center. In the center the converging air is swirling and moving upwards. The rising air condenses, forms clouds, and releases latent heat that heats the core of the storm

  1. There are some surface conditions that influence cyclogenesis, but the real key to mid-latitude cyclone development lies in the winds aloft. How are mid-latitude cyclones influenced by upper-level flow? Directly above the surface low, the airflow spreads out and diverges. This allows the converging surface air to rise and flow out of the.
  2. A surface ridge lies across the N Gulf while an elongated upper- level low is near the Texas-Louisiana border at 32N93W. Interaction between convergent surface SE winds related to the ridge and divergent winds associated with the low is triggering scattered showers and thunderstorms from the SW Texas coast across the NW Gulf to the Panhandle
  3. 2 The wind cannot be assumed to be geostrophic, or even quasi- geostrophic. The dynamic link between divergence/convergence and vorticity tendency is much weaker than in higher latitudes. Circulations must be much larger in order to be affected by rotation of the Earth. One manifestation of this is that land/sea breezes penetrate further inland in Tropics than in midlatitudes

Upper Level Wind Flow • Where the isobars (and wind flow) get closer together the air is converging, while when the isobars get further apart the air is diverging. Vertical Structure • A surface high will intensify if there is converging air above it. • A surface low will intensify if there is diverging air below it. • Note offset betwee For the cyclone to intensify, the diverging air aloft has to be greater than the converging air at the surface. This essentially pulls more air upwards and the surface pressure of the system drops.

Light breezes and 1 to 2 ft seas are noted across the northeast Gulf under the ridge axis. Fresh SE winds are noted over the northwest Gulf, between the ridge and lower pressure over Mexico. A surface trough is analyzed off the west coast of the Yucatan Peninsula, supporting fresh NE to E winds over the eastern Bay of Campeche For precision cleaning applications, SS-GLC operates by flowing high-pressure air or nitrogen through a throttling valve to the nozzle. Water is injected into the gas flow stream through an inlet orifice upstream of the converging/ diverging section of the nozzle. The nozzle design is based on an area ratio (ratio of exit area to the throat area) of 5.44 which gives a Mach number of 3.14. Such a mechanism can be surface winds converging along the ITCZ, a tropical easterly wave, or a pre-existing system such as an old mid-latitude front. Sufficient Coriolis force. That requirement does not fulfill near the equator, between about 3 °N and 3 °S because Coriolis force is zero at the equator

The converging water has nowhere to go but down, so the surface water sinks. Since surface water is usually low in nutrients, downwelling leads to low productivity zones. An example of a downwelling region is off of the Labrador coast in Canada, where the Gulf Stream, Labrador, and East Greenland Currents converge Fresh to strong NE winds are noted east of 25N, with reaching gale force of Morocco, with 7 to 10 ft seas. Elsewhere over the eastern Atlantic, gentle to moderate NE winds and 5 to 7 ft seas persist. For the forecast, winds and seas over the tropical Atlantic west of 35W will diminish through tonight

Currents Tutorial. Winds blowing across the ocean surface often push water away from an area. When this occurs, water rises up from beneath the surface to replace the diverging surface water. This process is known as upwelling. This graphic shows how displaced surface waters are replaced by cold, nutrient-rich water that wells up from below climate - climate - Cyclones and anticyclones: Cyclones and anticyclones are regions of relatively low and high pressure, respectively. They occur over most of Earth's surface in a variety of sizes ranging from the very large semipermanent examples described above to smaller, highly mobile systems. The latter are the focus of discussion in this section

When the SST was decreased by 5°C uniformly for all grids in the model, the winds calculated became divergent in the lower troposphere and convergent in the upper troposphere, creating conditions in which the amount of total latent heat release (TLHR) was low and the tropical cyclone (TC) could not be formed The wind field of Surigae is very big. Its hurricane-force winds are spread across the radius of 50-70 miles, while tropical-storm-force winds are reaching out to 105 miles around the dead center of the typhoon. Notice how the gale-force winds (34 knots) are brushing the eastern Philippines, about 200 miles away from the center This would then be the first Category 5 system on Earth this year. The last tropical cyclone that struck the Philippines was a real monster, a Category 5 typhoon Goni.

Strong winds increased turbulent fluxes and the wind field modified the sea ice cover as convergent winds increased IC, while the average sea ice motion was divergent. Since the wind was related to I and D, also these variables were related to surface conditions • Upper-level divergent geostrophic winds, which generates anticyclonic relative vorticity building the upper-level ridge downstream • Surface pressure falls in response to upper-level divergent forcing • Ageostrophic wind convergence acceleration at the surface • Convergence generates cyclonic vorticity at low level

If the upper levels are favorable for cyclone development, then there is a region of divergence aloft above the developing Low-pressure center. This will help pull the air that is converging at the surface upward and continue to develop the surface cyclone. (The upper levels also steer the system and make it progress east (like we learned. winds near the ocean surface blowing from different directions converging and causing air to rise and storm clouds to form; winds which do not vary greatly with height - known as low wind shear. This allows the storm clouds to rise vertically to high levels; sufficient distance from the equator to provide spin or twist Near the surface, the wind is slowed by friction on the ocean and tangential acceleration cannot compensate for the force that attracts air to the central depression. The resulting radial acceleration produces a converging flow in the lower layers, directed towards the centre of the cyclone, which feeds the rising currents. Figure 6

The surface systems move in about the same direction as the 500 mb flow, at about 1/2 the speed. Upper-level winds are about twice as strong in winter than summer. This results in stronger pressure gradients (and winds), resulting in stronger and more rapidly moving surface cyclones b. surface currents are deflected to the right of the direction the wind blows. c. winds from the north create surface currents directed away from the shore. d. erosion of the shoreline is likely greatest when winds blow from the south because of onshore flow of surface currents and wave action. 13 For instance, Milliff et al. (2004) first pointed out that, since rain occurs typically in convergent and cyclonic winds, failing to measure winds during rain naturally biases the mean divergence and vorticity toward the divergent and anticyclonic

Relatively cold surface waters chill the overlying humid marine air to saturation so that thick fog develops. Upwelling cold water inhibits formation of tropical cyclones (e.g., hurricanes), because tropical cyclones derive their energy from warm surface waters The MJO is associated with variations in sea surface temperature, organized precipitation, low-level winds, vertical wind shear, and atmospheric humidity and temperature, important factors in tropical cyclone formation and maintenance. Forecasts of the MJO at 2-3 week lead times might aid in forecasting periods of enhanced tropical cyclone. Cyclones move eastward in the Northern Hemisphere carried by prevailing winds. Cyclones last several days to a week. Depicted as an L on the weather map, cyclones bring rain and wind to an area. Cyclones are fueled by the temperature differences (hence pressure gradients) that exist along frontal boundaries Q. The weather map shows a zone of possible flash flooding in front of a cold front.

For mid-latitude cyclones and anticyclones to maintain themselves or intensify, the winds aloft must blow in such a way that zones of converging and diverging air form. Divergence is the process whereby more air is leaving a region than is entering that region. When this happens at the top of the troposphere it removes air molecules from that. the winds converging on the equatorial low-pressure trough. surface air diverging from the subtropical high-pressure cells generate Earth's principal surface winds: trade winds & westerlies. the eastern sides of these anticyclonic systems are drier and more stable and feature cooler ocean currents than do the western sides diverging surface winds and low pressure aloft. descending air and low pressure aloft. converging air, precipitation, and high pressure aloft.

The mT air mass may produce an occasional northeaster in the winter Surface winds in a cyclone in the Southern Hemisphere spiral inward and counterclockwise . Surface high pressure zones are usually associated with diverging. The usual configuration for a converging diverging (CD) nozzle is shown in the figure. Gas flows through the nozzle from a region of high pressure (usually referred to as the chamber) to one of low pressure (referred to as the ambient or tank). The chamber is usually big enough so that any flow velocities here are negligible A source of warm, moist air derived from tropical oceans with sea surface temperature normally near to or in excess of 27 °C. Winds near the ocean surface blowing from different directions converging and causing air to rise and storm clouds to form Winds which do not vary greatly with height - known as low wind shear The flow within the surface Ekman layer associated with the action of the wind is convergent in anticyclonic flow and divergent in cyclonic flow if the apparatus is rotating cyclonically (Ω > 0, corresponding to the northern hemisphere), as sketched in Figure 2. The convergent flow drives downward vertical motion (called Ekman pumping, Figure. Wind shear occurs when surface-level and higher-level winds are blowing at different speeds or in different directions. Extra-tropical (or mid-latitude) cyclones, which can produce weather ranging from mild rainstorms to violent blizzards, are even broader storms that typically begin in the middle or high latitudes


Divergent vs Convergent Winds? - Answer

The moist air rises and cools off, making clouds form. The heat from the ocean and the water evaporating from the surface make the whole system of clouds and wind spin and grow. The system rotates faster and faster, and an eye forms in the middle. The eye is calm. If the rotating winds reach 39 miles per hour, the storm is called a tropical storm Global Wind Explained. The illustration below portrays the global wind belts, three in each hemisphere. Note that the U.S. lies primarily in the Westerly Wind Belt with prevailing winds from the west. Each of these wind belts represents a cell that circulates air through the atmosphere from the surface to high altitudes and back again Cold currents Without the Coriolis force, surface winds cannot gain sufficient rotation to converge and the low pressure of the disturbance cannot be maintained. Large values of vertical wind shear disrupt the formation of a tropical cyclone by interfering with the organization of deep convection around the cyclone center. Wind shear- refers to.

View raw image; Velocity components used for the description of the tornado near-surface wind field. The circular velocity component υ cir is the vector sum of the radial υ r and tangential υ θ velocity components. The total velocity υ at a point of the tornado wind field follows from the superposition of υ cir and the translation speed υ trans.Further, α denotes the angle between the. For sea-level pressure to change, either convergence or divergence must get the upper hand within an air column. For a modestly developing low-pressure system (sea-level pressure decreases in time), the total amount of air diverging from the low's central air column at high levels (a weight loss) must exceed the total amount of air converging into the low's central air column at low levels (a. Of course, the winds are weaker directly in the shadows (wakes) of the mountains, so great differences in wind speeds at the ocean surface can lead to localized areas of divergent waters, causing upwelling, and convergent waters, causing downwelling (Figure 4)

A biconvex lens behaves as a converging lens in air because the refractive index of the material of the lens is greater than the refractive index of the air. The refractive index of the material of the lens (1.5) is also greater than the refractive index of water (1.33). So, it will behave as a converging lens Hurricanes are tropical cyclones with maximum sustained surface winds of at least 118 kilometres per hour. Hurricanes are known as typhoons in the western Pacific, very severe cyclonic storms in the North Indian Ocean, and severe tropical cyclones in Australia. There are 5 classes of hurricane intensity as outlined by the Saffir-Simpson Scale They are the first waves to form when the wind blows over the surface of the water and are created by the friction of wind and the surface tension of the water. These tiny little waves increase the surface area of the sea surface and if the wind continues to blow, the size of the wave will increase in size and become a wind wave
