RISThe Indo-U.S. Workshop on Weather and Climate Modeling
Publisher: American Meteorological Society
Abstract: A workshop on Weather and Climate Modelling, held in New Delhi (7?9 February 2002), India, under the aegis of the Indo?U.S. Science and Technology Forum brought together scientists involved in weather and climate modeling ...
Application of Extended Empirical Orthogonal Function Analysis to Interrelationships and Sequential Evolution of Monsoon Fields
Publisher: American Meteorological Society
Abstract: Extended empirical orthogonal function (EEOF) analysis has been employed to study linear relationships among the mean sea level pressure, 700 mb height and rainfall over India, and their low-frequency sequential evolution ...
Potential Predictability of Lower-Tropospheric Monsoon Circulation and Rainfall over India
Publisher: American Meteorological Society
Abstract: The potential predictability of the lower tropospheric circulation and the rainfall over India during the peak summer monsoon season (July?August) is studied by analyzing the signal-to-noise ratio. Daily 700-mb heights, ...
An Operational Model for Forecasting Probability of Precipitation and Yes/No Forecast
Publisher: American Meteorological Society
Abstract: An operational system for forecasting probability of precipitation (PoP) and yes/no forecast over 10 stations during monsoon season is developed. A perfect prog method (PPM) approach is followed for statistical interpretation ...
Possibility of Predicting Indian Monsoon Rainfall on Reduced Spatial and Temporal Scales
Publisher: American Meteorological Society
Abstract: Three selected parameters have been analyzed for the spatial and temporal relationships with the Indian monsoon rainfall. These parameters are (i) the subtropical ridge position at 500 hPa over India in April, (ii) ...
Interannual Variability of the Madden-Julian Oscillations in Indian Summer Monsoon Rainfall
Publisher: American Meteorological Society
Abstract: The Madden-Julian oscillations are quite prominent over the Indian monsoon region and they are related with the large-scale active-break phases of the monsoon. These oscillations, however, show considerable inter-annual ...
Synoptic Climatology of the Daily 700 mb Summer Monsoon Flow Patterns over India
Publisher: American Meteorological Society
Abstract: The daily (mean of 0000 and 1200 GMT) 700 mb contour patterns over India are classified in five broad types for each summer monsoon month by using a chart-to-chart correlation method. Certain characteristics of these ...
Forecasting Maximum and Minimum Temperatures by Statistical Interpretation of Numerical Weather Prediction Model Output
Publisher: American Meteorological Society
Abstract: The inability of a general circulation model (GCM) to predict the surface weather parameters accurately necessitates statistical interpretation of numerical weather prediction (NWP) model output. Here a system for forecasting ...
Mesoscale Modeling for Mountain Weather Forecasting Over the Himalayas
Publisher: American Meteorological Society
Abstract: Severe weather has a more calamitous effect in the mountainous region-because the terrain is complex and the economy is poorly developed and fragile. Such weather systems occurring on a small spatiotemporal scale invite ...
