Thermodynamic and Radiative Impact of the Correction of Sounding Humidity Bias in the Tropics
Publisher: American Meteorological Society
Abstract: Accurate measurements of atmospheric water vapor are crucial to many aspects of climate research and atmospheric science. This paper discusses some of the meteorological implications of a bias discovered in the measurement ...
Recovery Processes and Factors Limiting Cloud-Top Height following the Arrival of a Dry Intrusion Observed during TOGA COARE
Publisher: American Meteorological Society
Abstract: This study investigates the recovery of the tropical atmosphere to moist conditions following the arrival of a dry intrusion observed during the Tropical Ocean and Global Atmosphere Program Coupled Ocean?Atmosphere Response ...
Coevolution of Down-Valley Flow and the Nocturnal Boundary Layer in Complex Terrain
Publisher: American Meteorological Society
Abstract: An enhanced National Center for Atmospheric Research (NCAR) integrated sounding system (ISS) was deployed as part of the Vertical Transport and Mixing (VTMX) field experiment, which took place in October of 2000. The ...
Structure and Evolution of the 22 February 1993 TOGA COARE Squall Line: Numerical Simulations
Publisher: American Meteorological Society
Abstract: In this study a numerical cloud model is used to simulate the three-dimensional evolution of an oceanic tropical squall line observed during the Tropical Ocean Global Atmosphere Coupled Ocean?Atmosphere Response Experiment ...
Four-Dimensional Variational Data Assimilation of Heterogeneous Mesoscale Observations for a Strong Convective Case
Publisher: American Meteorological Society
Abstract: On 19 September 1996, a squall line stretching from Nebraska to Texas with intense embedded convection moved eastward across the Kansas?Oklahoma area, where special observations were taken as part of a Water Vapor Intensive ...
Flow-Dependent Reliability: A Path to More Skillful Ensemble Forecasts
Publisher: American Meteorological Society
Abstract: AbstractWhile chaos ensures that probabilistic weather forecasts cannot always be ?sharp,? it is important for users and developers that they are reliable. For example, they should not be overconfident or underconfident. ...
Interactions of Tropopause Depressions with an Ex–Tropical Cyclone and Sensitivity of Forecasts to Analysis Errors
Publisher: American Meteorological Society
Abstract: This paper focuses on the coupling between an ex?tropical cyclone and two preexisting mesoscale tropopause depressions (TDs). The TDs approached the cyclone from widely separated sources after becoming cut off from different ...
THORPEX Research and the Science of Prediction
Publisher: American Meteorological Society
Abstract: he Observing System Research and Predictability Experiment (THORPEX) was a 10-yr, international research program organized by the World Meteorological Organization?s World Weather Research Program. THORPEX was motivated ...
