WebThis causes a directional change in the wind speed (ageostrophic flow). Once the air moves on the lee-ward side of the mountains it no longer experiences the friction. The friction over the mountains creates a shortwave that advects … WebThey usually result from a strong short wave moving south on the west side of troughs that extended the trough toward the equator. The momentum of the short wave pulls the trough out of the main airflow and forms a closed, low pressure, circulation.

WebDec 9, 2024 · Troughs are marked with a black dashed line, and ridges with a white zig-zag line. 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. WebBecause they are much smaller than longwaves, shortwave troughs often have a much sharper curvature than longwaves and hence stronger divergence and forced rising motion. Thus, shortwaves can indicate the …
