An evaluation of satellite-derived humidity and its relationship to convective development. By Henry E. Fuelberg. Abstract. An aircraft prototype of the High-Resolution Interferometer Sounder (HIS) was flown over Tennessee and northern Alabama during summer The HIS temperature and dewpoint soundings were examined on two flight days to Convective temperatures derived from HIS retrievals helped explain the cloud formation that occurred after the HIS overflights.
Crude estimates of Bowen ratio were obtained from HIS data using a mixing-line approach. Values indicated that areas of large sensible heat flux were the areas of first cloud :// Get this from a library.

e s is the liquid water saturation vapor pressure at air temperature, given approximately by the empirical equation The satellite instrument exhibits its maximum sensitivity to detect differences in humidity near the level where the atmospheric contribution intersects the surface contribution.
The crossover effect causes the net radiation intensity in the μm band of Meteosat to be very sensitive within mid- and upper troposphere moist layers (see The expected pattern [as reported by Krishnamurthy and Shukla (), Guhathakurta and RajeevanJoshi et al. (), and Mishra et al.

Such a quasi-geostrophic approach can be used for the purposes of subjective analysis to diagnose the vertical circulation associated with a large-scale distribution of pressure and temperature Ma, W., M.
