Abstract
Precipitation relative to the 300-mb jet is studied through the patterns formed by 24-hr rainfall amounts in 57 synoptic situations. Definite patterns are found and a brief statistical consideration given of the position of maximum precipitation relative to the center of strongest winds. It is found, when allowance is made for latitudinal variations in the availability of moisture, that the precipitation tends to be a maximum underneath the jet. Situations with open troughs of small amplitude are compared with cases of almost pure zonal flow.
