RISA Further Study on Estimating Surface Evaporation Using Monthly Mean Data: Comparison of Bulk Formulations
Publisher: American Meteorological Society
Abstract: This study further examines the errors in estimating surface evaporation using monthly mean surface atmospheric variables from the moored buoys in the equatorial Pacific. Results from two significantly different bulk ...
Lagrangian Study of Cloud Properties and Their Relationships to Meteorological Parameters over the U.S. Southern Great Plains
Publisher: American Meteorological Society
Abstract: Hourly satellite cloud data from 18 June to 18 July 1997 over the U.S. southern Great Plains are analyzed to study the scale-dependent cloud properties and their relationships to atmospheric conditions. The observed clouds ...
Effects of Cumulus Convection on the Simulated Monsoon Circulation in a General Circulation Model
Publisher: American Meteorological Society
Abstract: The effect of cumulus convection on the Asian summer monsoon circulation is investigated, using a general circulation model. Two simulations for the summer months (June, July, and August) are performed, one parameterizing ...
Use of Monthly Mean Data to Compute Surface Turbulent Fluxes in the Tropical Pacific
Publisher: American Meteorological Society
Abstract: This study investigates to what extent monthly mean surface meteorological variables can be used to estimate surface turbulent fluxes in the equatorial Pacific. The two-year data from the TOGA TAO moored buoy array are ...

Abstract: AbstractDuring boreal spring, observations show a double ITCZ over the eastern Pacific, with the northern ITCZ stronger than the southern ITCZ. However, it is opposite in most climate models. It is also evident that there ...
Improving Trigger Functions for Convective Parameterization Schemes Using GOAmazon Observations
Publisher: American Meteorological Society
Abstract: AbstractUsing observations from the Green Ocean Amazon (GOAmazon) field campaign, this study aims to improve trigger functions of convection schemes. Results show that the CAPE generation rate (dCAPE)-type triggers are the ...

Abstract: AbstractObservational studies suggest that the vertical structure of diabatic heating is important to MJO development. In particular, the lack of a top-heavy heating profile was believed to be responsible for poor MJO ...
Convection Parameterization, Tropical Pacific Double ITCZ, and Upper-Ocean Biases in the NCAR CCSM3. Part I: Climatology and Atmospheric Feedback
Publisher: American Meteorological Society
Abstract: The role of convection parameterization in the formation of double ITCZ and associated upper-ocean biases in the NCAR Community Climate System Model, version 3 (CCSM3) is investigated by comparing the simulations using the ...
Convection Parameterization, Tropical Pacific Double ITCZ, and Upper-Ocean Biases in the NCAR CCSM3. Part II: Coupled Feedback and the Role of Ocean Heat Transport
Publisher: American Meteorological Society
Abstract: This study investigates the coupled atmosphere?ocean feedback and the role of ocean dynamic heat transport in the formation of double ITCZ over the tropical Pacific in the NCAR Community Climate System Model, version 3 ...
Evaluation of Trigger Functions for Convective Parameterization Schemes Using Observations
Publisher: American Meteorological Society
Abstract: ealistic simulation of different modes of atmospheric variability ranging from diurnal cycle to interannual variation in global climate models (GCMs) depends crucially on the convection trigger criteria. In this study, ...
