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 کاملThe effect of environmental conditions on tropical deep convective systems observed from the TRMM satellite
This study uses measurements of radiation and cloud properties taken between January and August 1998 by three Tropical Rainfall Measuring Mission (TRMM) instruments, the Clouds and the Earth’s Radiant Energy System (CERES) scanner, the TRMM Microwave Imager (TMI), and the Visible and InfraRed Scanner (VIRS), to evaluate the variations of tropical deep convective systems (DCS) with sea surface t...
متن کاملConvective and large‐scale mass flux profiles over tropical oceans determined from synergistic analysis of a suite of satellite observations
A new, satellite-based methodology is developed to evaluate convective mass flux and large-scale total mass flux. To derive the convective mass flux, candidate profiles of in-cloud vertical velocity are first constructed with a simple plume model under the constraint of ambient sounding and then narrowed down to the solution that matches satellite-derived cloud top buoyancy. Meanwhile, the larg...
متن کاملModeling of rainfall enhancement by seeding tropical convective clouds
Convective clouds are characterized by strong updrafts, enhanced transport of heat and moisture in the upper layers and rainfall processes which are activated in very limited time interval and space and with a variable intensities. The cloud seeding for rain enhancment of such clouds is a big challenge and common practice in many areas over the world for more than 50 years. There is a strong sc...
متن کاملRelationship between surface conditions and subsequent rainfall in convective storms
This paper describes the relationship between surface conditions (temperature and humidity) and subsequent rainfall. The focus is on convective storms that are forced and maintained locally due to conditional instability in the vertical distribution of atmospheric temperature. These storms are described using two probabilistic measures: (1) the probability of occurrence of storms given surface ...
