      In some of the studies, the prediction of Indian summer monsoon rainfall is being improved by superensemble and downscale method [25–28]. In the present study, we worked with rainfall anomalies and the skills were compared among the best models (ECMWF model comes out best among 16 suites of models for Indian region, Kumar and Krishnamurti Author: Vinay Kumar, Tirthankar Ghosh. monsoon rainfall using regional coupled models for the Indian and African monsoon (e.g. Hagos and Cook, ; Ratnam etal., ; Ratnam., ). These studies also show that the regional coupled models improve the ocean circulation as compared with the standalone ocean model. In this study, we have developed a regional cou-Cited by:

        The Indian summer monsoon (ISM), as an important component of the global monsoon system, is driven by cross-equatorial pressure gradient (XEPG) between the Indian low over the Asian continent and the Mascarene high in the southern Indian Ocean (1, 2).This is a uniquely coupled, bi-hemispheric system; nowhere else on Earth does cross-equatorial transfer of heat and momentum Cited by: The model was run from May to October each year, and the analysis was performed for the Indian Summer Monsoon (June-July-August-September, JJAS) months, thus allowing for one month of spin-up (May) time each by:

        The importance of Indian Summer Monsoon Rainfall (ISMR) for agricultural production, water availability, and food security is well-documented ().Interannual monsoon variability strongly affects agricultural production, which accounts for about 22% of the Indian gross domestic product ().Disruptions in the ISMR can lead to substantial losses in crop production that, in turn, may affect the Cited by:   For the first time, researchers from the Indian Institute of Technology (IIT) Bombay have found that even a change in irrigation policy has the potential to shift monsoon rainfall and intensify Location: Kasturi Building, Anna Salai, , Mount Road, Chennai, , Tamil Nadu.

Of prolonged break (inactive) spells during the monsoon rainy season. The daily time series of the all-India summer monsoon precipitation (Fig. 1b) shows three major break spells (i.e., the first one in the third week of June; the second was an intense and long dry spell extending from the third week of July until the.

[1] The Indian summer monsoon (ISM) influences daily lives and economies in many countries in the South Asian region. This study analyzes the representation of the ISM system in the regional climate model COSMO‐CLM.

The study aims to evaluate the regional climate model (RegCM) over South Asian (SA) CORDEX domain to represent seasonal and sub-seasonal variability of Indian Summer Monsoon (ISM).

The study mainly investigates sea surface temperature (SST) and outgoing longwave radiation (OLR) relationships in coupled climate model. To support the analysis, high-level cloud and OLR relationship is also investigated.

High-level cloud and OLR relationship depicts significant negative correlation over the entire monsoon regime.

Coupled climate model is able to produce the by: 3. Observations show that summer rainfall over large parts of South Asia has declined over the past five to six decades. It remains unclear, however, whether this trend is due to natural variability Cited by: Recent studies have already investigated the overall future changes in global monsoon precipitation using multi-model ensemble and/or selected CMIP5 models under different range of RCP scenarios (Hsu et al.,Hsu et al.,Wang et al.,Kitoh et al.,Lee and Wang, ), that suggest notable increase in global monsoon Cited by:   INTRODUCTION.

The Indian summer monsoon (ISM) is a large land-ocean-atmosphere coupled system that transports substantial amounts of moisture during boreal summer across the Indian Ocean into the Indian subcontinent, reaching as far northwest as Pakistan and as far north as the southern Himalayas ().The lives of billions of people in the Indian subcontinent are tightly Cited by: IITM Silver Jubilee Award Lecture on “Internal feedbacks from monsoon and mid-latitude interactions during droughts in the Indian summer monsoon”, 17 NovIITM, Pune.

Observational and modeling studies have identified an El Niño Southern Oscillation (ENSO) like Ocean-Atmospheric coupled phenomenon in the tropical Atlantic during the boreal summer season, popularly known as Atlantic Zonal Mode (AZM).

The atmospheric teleconnection between the AZM and Indian Summer Monsoon Rainfall (ISMR) is significant especially in non-ENSO by: 2. Analysis of the Indian summer monsoon system in the regional climate model COSMO-CLM.

The Indian summer (southwest) monsoon is referred as lifeline of India, as ariability in any of its aspects (onset, withdrawal and quantum of rainfall) greatly influences the agriculture yield, economy, water resources, power generation and ecosystem.
