Ship-based Radar and Sounding Measurements in Support of PISTON
Abstract
This PISTON research targets convection over land and offshore from the western Philippines, where tropical rainfall is hypothesized to occur because of southwesterly monsoonal flow impinging on the coastal mountain range. A complicated pattern of rainfall results, in part due to modulation by the boreal summer intraseasonal oscillation (BSISO). The main goal of this study is to better understand the physical processes governing interactions of coastal diurnal rainfall variability with the monsoon, the BSISO, ocean variability including sea-surface temperature (SST), and topography over land. This study will consider a broad range of scales from the large-scale BSISO to mesoscale and convective processes, using radiosonde data and a state-of-the-art ship-based polarimetric Doppler radar (SEA-POL; under development at CSU). The research will center on two key observational aspects: ship-based operation of the CSU SEA-POL C-band polarimetric Doppler radar; and ship-based operation of the CSU Vaisala sounding system, as well as coordinated multi-nation, land-based radar and upper-air sounding observations. Possible inter-agency and international coordination through the Years of the Maritime Continent (YMC) field campaign and NASA CAMPEx will also be conducted for land-based, ship-based and research aircraft-based observations, quality control, analysis, and synthesis.
