RISVariability of Moisture in the Upper Troposphere As Inferred from TOVS Satellite Observations and the ECMWF Model Analyses in 1989
Publisher: American Meteorological Society
Abstract: Large-scale variability of moisture in the upper troposphere is examined using TIROS (Television Infrared Observation Satellite) Operational Vertical Sounder (TOYS) satellite observations and ECMWF model analyses from 1989 ...
In Situ Observations of Temperature Microstructure above and below the Tropopause
Publisher: American Meteorological Society
Abstract: In this paper, the small-scale (<1 km) structure of temperature near the tropopause, as indicated by ozone concentration, is examined using data recorded during GALE from the NCAR Sabreliner. A systematic difference is ...
Changes in Twentieth-Century Extreme Temperature and Precipitation over the Western United States Based on Observations and Regional Climate Model Simulations
Publisher: American Meteorological Society
Abstract: rends in extreme temperature and precipitation in two regional climate model simulations forced by two global climate models are compared with observed trends over the western United States. The observed temperature extremes ...
Subsidence and Upper-Tropospheric Drying along Trajectories in a General Circulation Model
Publisher: American Meteorological Society
Abstract: A trajectory analysis of the Community Climate Model version 3 (CCM3) moisture simulation is used to show that the model simulates upper-tropospheric moisture observations better than would be inferred from a traditional ...
Extreme Precipitation and Temperature over the U.S. Pacific Northwest: A Comparison between Observations, Reanalysis Data, and Regional Models
Publisher: American Meteorological Society
Abstract: xtreme precipitation and temperature indices in reanalysis data and regional climate models are compared to station observations. The regional models represent most indices of extreme temperature well. For extreme ...
A Trajectory Analysis of Tropical Upper-Tropospheric Moisture and Convection
Publisher: American Meteorological Society
Abstract: It is shown that the distribution of upper-tropospheric humidity (UTH) in the cloud-free Tropics can be simulated with a simple model in which air expelled from moist convective regions is dried by subsidence along its ...
Evaluation of WRF and HadRM Mesoscale Climate Simulations over the U.S. Pacific Northwest
Publisher: American Meteorological Society
Abstract: This work compares the Weather Research and Forecasting (WRF) and Hadley Centre Regional Model (HadRM) simulations with the observed daily maximum and minimum temperature (Tmax and Tmin) and precipitation at Historical ...
Evaluation of the Upper-Tropospheric Moisture Climatology in a General Circulation Model Using TOVS Radiance Observations
Publisher: American Meteorological Society
Abstract: TOVS satellite observations are used to evaluate the upper-tropospheric (400?200 mb) moisture distribution simulated by the GLA GCM in a 10-yr (1979?1988) integration produced for the Atmospheric Model Inter-comparison ...
Changes in Winter Atmospheric Rivers along the North American West Coast in CMIP5 Climate Models
Publisher: American Meteorological Society
Abstract: ost extreme precipitation events that occur along the North American west coast are associated with winter atmospheric river (AR) events. Global climate models have sufficient resolution to simulate synoptic features ...
Statistical Precipitation Downscaling over the Northwestern United States Using Numerically Simulated Precipitation as a Predictor
Publisher: American Meteorological Society
Abstract: This study investigates whether GCM-simulated precipitation is a good predictor for regional precipitation over Washington and Oregon. In order to allow for a detailed comparison of the estimated precipitation with ...
