[--MAIN HOME--] [--ALL HABYHINTS--] [--FACEBOOK PAGE--] RAIN SOUNDING Radiosonde is launched into deep layer of precipitation, rain at surface Temperature will be near dewpoint in all layers There will not be much further evaporative cooling since air is already or nearly saturated Temperature and dewpoint may slightly diverge with height. Dewpoint becomes more difficult to calculate at low pressures and low temperatures (at temperatures below freezing frost point is higher than dewpoint also). EXAMPLE:
