About the Edition

On 2 April 1997, strong winds blew through the central coast of California that were accompanied by an intense jet streak and upper front. The event was analyzed with standard synoptic scale DIFAX charts and mesoscale charts for comparison. The mesoscale model used was the Coupled Ocean/Atmosphere Mesoscale Prediction System (COAMPS) developed by Naval Research Laboratory (NRL), Monterey, California. COAMPS captured features that were not diagnosed on the synoptic charts. Height, isotach and temperature fields showed more detail, although observations were not sufficient to completely verify the model"s level of detail. COAMPS was heavily influenced by the topographic field modeling lee troughs and mountain waves along the Sierra Nevada mountains. A strong mountain wave, initiated by the upper front, occurred in central California during this time period. The wave troughs correlated to wind maxima at the surface, including one near San Francisco Bay where winds as high as 66 mph were reported.

The wind's speeds generally increases with height above the earth's surface because: a) only the lowest layer of air rotates with the earth b) air temperature normally decreases with height c) wind instruments are not accurate at the earth's surface d) friction with the earth's surface slows the air near the ground.

Finding Warm Fronts Using Wind Direction For example, below is a surface weather map with an analyzed low pressure center (red "L") and associated cold front (blue line) and warm front while behind the front, winds had shifted around and were blowing out of the south.

This sudden shift in wind direction was the key indicator that a warm. The California milliped genus Xystocheir Cook, occurring along the Pacific Coast and the western slope of the Sierra Nevada, comprises nine species, three being divided into a total of seven.

Note that west of the ridge axis, winds are from the southwest (a warm weather direction) and 5/5(1). The focus is on the spatial and temporal distribution of the ocean mixed layer response to the strong winds, and on how this is affected by atmosphere–ocean coupling.
