Planetary waves in the troposphere and lower stratosphere over Fort Worth (32.8°N, 97.3°W)

摘要：

In this paper, the planetary waves (PWs) over Fort Worth (32.8°N, 97.3°W) are investigated on the basis of the radiosonde measurements with 0-30 km height region during 1998-2006. The observations show that PWs exist in two regions. One is in the troposphere, and the other is in the stratosphere. In the troposphere, the amplitudes of the PWs reach maximum round the center of the subtropical jet stream. The subtropical jet stream may be one of the PW excitation sources. However, in the stratosphere, only the lower frequency PWs remain in winter, with the zonal component strongest. Moreover, the PW activities are rather intermittent, and their lifetimes are not longer than two months.
