Adjustment to precip. water

Post by MMWeather »

Have not been happy with previous PW script. Have searched online and have found estimates that include the Grav. Constant. When I have included that into the equation the numbers are way off. This script like the orig. is just an estimate. I just ran this and checked with the spc site. except for the really low values out west, everything east of the Miss. is very close. So here is the updated version that *appears* to be closer to reality. The SPC site shows "PW for lowest 400Mb" This script uses sfc to 500mb.
