Water Vapor Measurements Over the Eastern Pacific Ocean at the 180-Millibar Pressure Level.
Abstract
A frost-point hygrometer has been installed on the NASA C141 Flying Observatory to measure water vapor in the upper troposphere and lower stratosphere. Measurements were made during two flights in June 1974 in the region of the subtropical high-pressure cell over the eastern Pacific Ocean at an upper tropospheric pressure height of 180 mb. The relative humidity in the region was found to be high, implying that the subsidence characterizing the lower tropospheric level of the subtropical high is weak or nonexistent at the 180-mb level in early summer. Saturation of the level at times due to vertical oscillations seems likely.
