RISTropical Clouds and Circulation Changes during the 2006/07 and 2009/10 El Niños
Publisher: American Meteorological Society
Abstract: hanges in tropical cloud vertical structure, cloud radiative forcing (CRF), and circulation exhibit distinctly different characteristics during the 2006/07 and 2009/10 El Niños, revealed by CloudSat and Cloud?Aerosol Lidar ...
The Scatter in Tropical Average Precipitation Anomalies
Publisher: American Meteorological Society
Abstract: Tropical mean precipitation anomalies ?P?? for 3-month averages appear quite scattered in relation to tropical average sea surface temperature (SST) anomalies ?Ts??, based on examination of a number of observational datasets ...
Moist Teleconnection Mechanisms for the Tropical South American and Atlantic Sector
Publisher: American Meteorological Society
Abstract: Teleconnections have traditionally been studied for the case of dry dynamical response to a given diabatic heat source. Important anomalies often occur within convective zones, for instance, in the observed remote response ...
Teleconnection Mechanisms for Tropical Pacific Descent Anomalies during El Niño
Publisher: American Meteorological Society
Abstract: Teleconnection mechanisms in relative descent zones are examined using the quasi-equilibrium tropical circulation model (QTCM). The regions of anomalous descent neighboring the warm sea surface temperature (SST) anomalies ...
Self-Aggregation and Large-Scale Control of Tropical Deep Convection: A Modeling Study
Publisher: American Meteorological Society
Abstract: The Pennsylvania State University?National Center for Atmospheric Research Mesoscale Model version 5 (MM5) is used to investigate whether superclusters represent a mode of self-aggregation of tropical deep convection that ...
Sensitivity of Tropical Tropospheric Temperature to Sea Surface Temperature Forcing
Publisher: American Meteorological Society
Abstract: During El Niño, there are substantial tropospheric temperature anomalies across the entire tropical belt associated with the warming of sea surface temperatures (SSTs) in the central and eastern Pacific. The quasi-equilibrium ...
Sensitivity of Tropical Tropospheric Temperature to Sea Surface Temperature Forcing
Publisher: American Meteorological Society
Abstract: During El Niño, there are substantial tropospheric temperature anomalies across the entire tropical belt associated with the warming of sea surface temperatures (SSTs) in the central and eastern Pacific. The quasi-equilibrium ...
Mechanisms for Lagged Atmospheric Response to ENSO SST Forcing
Publisher: American Meteorological Society
Abstract: The mechanism and sensitivity of the lagged response of tropical tropospheric temperature to El Niño?Southern Oscillation (ENSO) SST forcing are examined using the Quasi-Equilibrium Tropical Circulation Model (QTCM) coupled ...
Two-Stage Artificial Intelligence Algorithm for Calculating Moisture-Tracking Atmospheric Motion Vectors
Publisher: American Meteorological Society
Three-Dimensional Week-Long Simulations of TOGA COARE Convective Systems Using the MM5 Mesoscale Model
Publisher: American Meteorological Society
Abstract: A three-dimensional nonhydrostatic mesoscale model, the Pennsylvania State University/National Center for Atmospheric Research mesoscale model (MM5), is used to simulate the evolution of convective systems over the intensive ...
