WebA shortwave trough can be defined in several ways. The following are characteristics that most shortwave troughs possess: (1) Shortwaves are smaller than longwave troughs. (2) … WebIn the spirit of 500-mb shortwave troughs, upper-level jet streaks help to prime the local environment for deep, moist convection. If nothing else, upper-level jet streaks promote high-altitude cooling via upward motion …

However, this flow is unstable, allowing small disturbances (e.g., flow over mountain ranges) to grow into large north-south meanders (Fig. 11.49b) of the jet stream. These meanders are called Rossby waves or planetary waves. Typical wavelengths are 3 - 4 Mm.

WebAug 15, 2024 · A trough is an elongated (stretched out) region of relatively low pressure, often associated with the passage of a low-pressure system, warm front, or cold front. A trough may be at surface, aloft, or in the upper troposphere. Longwave and shortwave troughs represent different patterns of atmospheric circulation.
