Abstract: An interpretation of the ?-equation shows that upward motion is closely related to the advection of vorticity in the upper troposphere and to warm advection in the lower troposphere. Examples are presented to illustrate ...

Abstract: A one-layer. one-dimensional numerical model is described which simulates the life cycle of the extratropical low-level jet (LLJ). The LLJ starts as an isallobaric wind near the point of maximum pressure tall. Subsequently, ...

Abstract: Satellite photographs of 5 May 1983 show arches of clouds over Nebraska and Kansas that resemble clouds on the outflow boundaries near thunderstorms. However, there were no thunderstorms to provide the outflow. The arches ...

Abstract: The accuracy of the horizontal meteorological trajectories is investigated in respect to several influential factors. The conclusions are based on ?objective? trajectories computed by the electronic computer. It was found ...

Abstract: The low-level jet (LLJ) in the winter half-year originates as a south wind over the high plains of Colorado. Kansas, western Oklahoma and West Texas. After formation, the LLJ spreads horizontally and upstream toward the ...

Abstract: On the basis of 20 cases in the winter half year, it is found that a southerly low-level jet (LLJ) is regularly associated with extratropical cyclones in the southwestern Great Plains. Only very weak and short-lived lows ...

Abstract: Improvements in computer technology, particularly the explosive growth of Internet applications, have created unprecedented educational opportunities, but with concomitantly little experience on how educators can best take ...
