Upper tropospheric dynamics as reflected in Nimbus 4 THIR 6.7-micron data

Abstract

An investigation was conducted of the spatial and temporal relationships existing between the radiometrically observed water vapor patterns in cloud free areas and the conventionally derived water vapor patterns. The upper and middle tropospheric water vapor budget and the associated dynamics were examined to obtain a basis for a more definite evaluation of the significance of the Nimbus 4 radiometric 6.7-micrometer observations for the study of tropospheric dynamics in cloud free areas. A large-amplitude trough situated to the lee of the Rocky Mountains over the central U.S. between April 30 and May 1, 1970, was selected for the investigation because it best illustrated large upper tropospheric dynamic variations.
