Dual-Polarization Radar Rainfall Estimation over Tropical Oceans
Dual-polarization radar rainfall estimation relationships have been extensively tested in continental and subtropical coastal rain regimes, with little testing over tropical oceans where the majority of rain on Earth occurs. A 1.5-yr Indo-Pacific warm pool disdrometer dataset was used to quantify the impacts of tropical oceanic drop-size distribution (DSD) variability on dual-polarization radar...
متن کاملTropical cyclone rainfall area controlled by relative sea surface temperature
Tropical cyclone rainfall rates have been projected to increase in a warmer climate. The area coverage of tropical cyclones influences their impact on human lives, yet little is known about how tropical cyclone rainfall area will change in the future. Here, using satellite data and global atmospheric model simulations, we show that tropical cyclone rainfall area is controlled primarily by its e...
متن کاملSimulated Sea Surface Salinity variability in the tropical Pacific
[1] Sea Surface Salinity (SSS) variability from a hindcast run of an oceanic general circulation model (OGCM) forced by daily NCEP-NCAR reanalysis from 1990 to 2001 is analyzed. The purpose is to test the capability of the model in terms of the salinity simulation and provide insights for the future SSS observation from space. With daily forcing, the model can reproduce SSS change of the tropic...
متن کاملEstimation of the Surface Heat Flux Response to Sea Surface Temperature Anomalies over the Global Oceans
The surface heat flux response to underlying sea surface temperature (SST) anomalies (the surface heat flux feedback) is estimated using 42 yr (1956–97) of ship-derived monthly turbulent heat fluxes and 17 yr (1984–2000) of satellite-derived monthly radiative fluxes over the global oceans for individual seasons. Net surface heat flux feedback is generally negative (i.e., a damping of the underl...
متن کاملSMOS: Measuring Sea Surface Salinity from Space
In May 1999, the European Space Agency (ESA) selected SMOS as an Earth Explorer Opportunity mission. One of its goals is the generation of global Sea Surface Salinity (SSS) maps. The sensor embarked is an L-band interferometric radiometer with full-polarimetric capability called MIRAS. The retrieval of SSS from microwave measurements is based on the fact that the brightness temperature (TB) of ...
