Diagnostic Modeling of the Indian Monsoon Onset. Part II: Budget and Sensitivity Studies
Publisher: American Meteorological Society
Abstract: A one-dimensional diagnostic coupled air?sea model (described in the companion paper) is applied to the analysis of the heat and moisture budgets over the Arabian Sea during the 1979 monsoon onset period. The surface energy ...
Diagnostic Modeling of the Indian Monsoon Onset. Part I: Model Description and Validation
Publisher: American Meteorological Society
Abstract: A new type of diagnostic model is developed and applied to the study of the onset of the Indian summer monsoon. The purpose of the model is to aid in the analysis of interactions between the physical processes that affect ...
Implications of Microphysics for Cloud-Radiation Parameterizations: Lessons from TOGA COARE
Publisher: American Meteorological Society
Abstract: A single-column model (SCM) and observational data collected during TOGA COARE were used to investigate the sensitivity of model-produced cloud properties and radiative fluxes to the representation of cloud microphysics ...
North Pacific Cloud Feedbacks Inferred from Synoptic-Scale Dynamic and Thermodynamic Relationships
Publisher: American Meteorological Society
Abstract: Daily satellite cloud observations and reanalysis dynamical parameters are analyzed to determine how midtropospheric vertical velocity and advection over the sea surface temperature gradient control midlatitude North Pacific ...
The Great 2006 Heat Wave over California and Nevada: Signal of an Increasing Trend
Publisher: American Meteorological Society
Abstract: Most of the great California?Nevada heat waves can be classified into primarily daytime or nighttime events depending on whether atmospheric conditions are dry or humid. A rash of nighttime-accentuated events in the last ...
Comparison of Four Cloud Schemes in Simulating the Seasonal Mean Field Forced by the Observed Sea Surface Temperature
Publisher: American Meteorological Society
Abstract: The impacts of four stratiform cloud parameterizations on seasonal mean fields are investigated using the global version of the Experimental Climate Prediction Center (ECPC) global-to-regional forecast system (G-RSM). The ...
Annual Drought in California: Association with Monthly Precipitation and Climate Phases
Publisher: American Meteorological Society
Abstract: nnual precipitation in California is more variable than in any other state and is highly influenced by precipitation in winter months. A primary question among stakeholders is whether low precipitation in certain months ...
Developing and Evaluating Drought Indicators for Decision-Making
Publisher: American Meteorological Society
Abstract: rought indicators can help to detect, assess, and reduce impacts of drought. However, existing indicators often have deficiencies that limit their effectiveness, such as statistical inconsistency, noncomparability, arbitrary ...
Sensitivity of Cloud and Radiation Parameterizations to Changes in Vertical Resolution
Publisher: American Meteorological Society
Abstract: The importance of vertical resolution to the parameterization of cloud?radiation processes in climate models is examined. Using a one-dimensional single-column model containing a typical suite of physical parameterizations, ...
Cloud Radiation Forcings and Feedbacks: General Circulation Model Tests and Observational Validation
Publisher: American Meteorological Society
Abstract: Using an atmospheric general circulation model (the National Center for Atmospheric Research Community Climate Model: CCM2), the effects on climate sensitivity of several different cloud radiation parameterizations have ...
