Web2 The main differences between the tropical atmosphere and the midlatitudes are: Coriolis parameter is small in Tropics. The implications of this are 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 …

The Effects Of Divergence & Convergence On Weather Systems

WebConfluence is not the same as convergence. Winds often accelerate as they enter a confluent zone, resulting in speed divergence which offsets the (apparent) … WebWhen the divergence in the upper levels is stronger than convergence at the surface, surface pressures will lower further, and the low will intensify and deepen. Put another way: when air exits the column more rapidly aloft than it enters the column at the surface, then the amount of air in the column will reduce, the surface pressure will ... Webically imply divergence and making that assumption can lead to incorrect estimates of the implied vertical motion. 2. Discussion Although the concepts of divergence and diffluence have existed for a long time (e.g., Petterssen 1956), confusion still remains in the application of these ideas in the operational setting. docketly conflicts

"WebDivergence aloft is associated with rising air throughout the troposphere, which is associated with low pressure and convergence at the surface. Convergence aloft is associated with sinking air throughout the troposphere, which is associated with high pressure at the surface and thus divergence at the surface.

If the opposite occurs, upward motion of air will be developed, leading to the formation of cloud and even rain. The concept of convergence and divergence is very ...

Webconstrained convergence to always produce cyclonic vorticity. This is okay on the synoptic scale, because negative absolute vorticity rarely if ever occurs at that scale. ο Keep in mind though, that on the mesoscale or smaller, the absolute vorticity must be used in the divergence term (we can’t ignore ζ ), and so it is possible on WebDivergence is maximized for an upper-level wave with the following characteristics: large amplitude short wavelength strong wind speed and wind shear (which are a function of the horizontal thermal gradient at …

WebConvergence is when wind moves toward a region such as in a low pressure system. What happens with wind at the Earth’s surface is coupled with air higher up in the atmosphere (aloft) and results in vertical air movement.

Convergence in a horizontal wind field indicates that more air is entering a given area than is leaving at that level. To compensate for the resulting "excess," vertical motion may result: upward forcing if convergence is at low levels, or downward forcing (subsidence) if ... docketing technicianWebJust like straight jet streaks, divergence and upward motion occur in the left-exit regions of cyclonically curved jet streaks.
