A Systems Perspective on the Environmental Prediction Enterprise
Publisher: American Meteorological Society
An Improved Parameterization for Simulating Arctic Cloud Amount in the CCSM3 Climate Model
Publisher: American Meteorological Society
Abstract: A simple alternative parameterization for predicting cloud fraction in the Community Climate System Model, version 3 (CCSM3) global climate model is presented. This formula, dubbed ?freeezedry,? is designed to alleviate ...
Formation and Limiting Mechanisms for Very High Sea Surface Temperature: Linking the Dynamics and the Thermodynamics
Publisher: American Meteorological Society
Abstract: The present study composites atmosphere and ocean conditions associated with ocean hot spots. Ocean hot spots are defined as regions where SST exceeds 29.75°C and that have an area greater than 1 ? 106 km2. The composite ...
Removing Satellite Equatorial Crossing Time Biases from the OLR and HRC Datasets
Publisher: American Meteorological Society
Abstract: The objective of this study is to examine the impacts from satellite equatorial crossing time (ECT) changes on the outgoing longwave radiation (OLR) and highly reflective cloud (HRC) datasets and to design appropriate and ...
A Satellite-derived Climatology of the ITCZ
Publisher: American Meteorological Society
Abstract: This paper presents fundamental climatological characteristics of the intertropical convergence zone (ITCZ) in a simple concise manner using the highly reflective cloud (HRC) dataset. This satellite-derived dataset uses ...
Preferred Latitudes of the Intertropical Convergence Zone
Publisher: American Meteorological Society
Abstract: The latitude preference of the intertropical convergence zone (ITCZ) is examined on the basis of observations, theory, and a modeling analysis. Observations show that convection is enhanced at latitudes of about 4° to 10° ...
Modulation of Tropical Cyclones over the Eastern Pacific by the Intraseasonal Variability Simulated in an AGCM
Publisher: American Meteorological Society
Abstract: his study illustrates that observed modulations of tropical cyclone (TC) genesis over the eastern Pacific (EPAC) by large-scale intraseasonal variability (ISV) are well represented in a recently developed high-resolution ...
Three-Dimensional Water Vapor and Cloud Variations Associated with the Madden–Julian Oscillation during Northern Hemisphere Winter
Publisher: American Meteorological Society
Abstract: The Madden?Julian oscillation (MJO) is the dominant form of intraseasonal variability in the Tropics. In previous studies, intraseasonal variability has usually been characterized in terms of wind or convection anomalies, ...
Modulation of the Convectively Coupled Kelvin Waves over South America and the Tropical Atlantic Ocean in Association with the Madden–Julian Oscillation
Publisher: American Meteorological Society
Abstract: n this study, evidence of the strong modulation of the convectively coupled Kelvin wave (CCKW) activity by the Madden?Julian oscillation (MJO) is presented, with a particular focus over the South America and tropical ...
