Abstract:

The fields of temperature, height, geostrophic wind, geostrophic vorticity, and the advection fields of vorticity, and temperature of the 700 to 500 mb atmospheric layer are studied in relationship to the area integrated monthly precipitation over the Colorado River Basin. The horizontal shear of the wind field in the layer and the position of the long wave ridge with respect to the basin are also shown to be related to the monthly precipitation. A multiple linear regression technique is used to determine those parameters which are most important in describing the monthly basin precipitation. An analysis of the long waves on monthly charts is shown. The fields of vorticity and temperature advection were used to evaluate the relationship between the fields of temperature and motion. With the restriction that the waves must be stationary the computed vertical motions over the Colorado River Basin agree quite well with those required by the restriction. Author
