CarSnowAmt

Overview

This tool uses upper level temperatures, vertical motion, and relative humidity to calculate a snowratio. The tool algorithm uses a blend of approaches based on the findings Dube`(2003), and also in part Waldstreicher(2001), and the top-down microphysical diagnostics of Baumgardt(2001). The derived snowratio is then multiplied by the QPF field to yield a snow amount. The tool is capable of producing snowratios from 0 to 25:1. Highest snowratios occur when vertical motion maxima coincide with snow production zone (i.e. temperatures between -12 and -18 Celsius).
