Proposal Type: General Category: Sub-Category: Observation Category: Total Time Requested: Minimum Useful Time: Prop osal Title: ABSTRACT:
We propose to continue our successful program for measuring momentum flux, wind variances of the horizontal and vertical wind components using the dual-beam capability of the Arecibo 430 MHz radar. Our proposed continuation would extend our observations down to the stratosphere in order to measure the coupling from the lower atmosphere. The observations will cover 15­35 km in the stratosphere and 70­95 km in the mesosphere, and we will seek correlations in the gravity wave activity in the two regions. Of particular interest are gravity waves associated with the frequent thunderstorm activity near Arecibo. Our proposed studies will extend momentum flux measurements to the meridional direction by swinging the beam. We plan to use statistical representations of momentum flux like probability distribution functions to enhance our understanding of the spectrum of waves present. The increased number of measurements will enhance of understanding of the climatology of gravity wave influences in the tropical region.
