The international foodstuff protection and sustainable agriculture are the most important demanding situations sooner than the medical group within the current period of improved weather variability, swiftly emerging inhabitants and dwindling assets. No a part of the area is immune from meteorological extremes of 1 style or one other posing hazard to the nutrition safeguard. Agrometeorology has to make best use of the possibilities to be had in attaining the targets of bettering productiveness and upkeep of sustainability. elevated wisdom and technological development have supplied possibilities to increase effective agrometeorological companies which could aid take care of hazards. those contain advancements in climate forecasting, higher knowing of the monsoon variability and crop-weather relationships, advances in operational agrometeorology and agrometeorological details structures, variation concepts to weather switch and better chance overview and administration. This publication in keeping with a global Workshop held in New Delhi, India might be of curiosity to all corporations and organizations drawn to agrometeorological applications

13 Daily standardised rainfall series simulated by individual ensembles at 30 km resolution compared with that of IMD (a) 2002 (b) 2003 weighted average rainfall over India is better simulated by the RegCM3 at higher resolution of 30 km and are more accuracy in comparison to 55 km resolution. 0 Dates Fig. 14 Daily standardised rainfall series simulated by individual ensembles at 55 km resolution compared with that of IMD (a) 2002 (b) 2003 2002 and 2003. 15 shows the daily accumulated rainfall simulated by RegCM3 with 30 and 55 km along with IMD daily rainfall time series, starting from 1st June up to 30th September.

9 July 2002 mean rainfall (cm) at the grids over Indian landmass (a) IMD 1-degree, (b) RegCM3 55 km and (c) RegCM3 30 km In July 2002 very little rain was observed except in the west coast and north-east of India (Fig. 9a) while in July 2003 good amount of rainfall was recorded throughout the country (Fig. 10a). This contrasting rainfall is clearly seen for higher resolution simulation of RegCM3 in comparison to resolution of 55 km. 9a, c show that there is good amount of rainfall in west coast, some parts of coastal Andhra, coastal Orissa, along the foothills of Himalayas and north east India whereas there is very less rainfall in north-west and some parts of central India while Fig.

2006) in this study, Grell convective precipitation scheme with ArakawaSchubert (AS) closure has been used. K. Dash et al. RegCM modeling frameworks. It is a mass flux scheme that includes the moistening and heating effects of penetrative updrafts and corresponding downdrafts. For simulating the monsoon circulation features the central grid point for model domain is chosen at 80 E and 20 N. In the 55 km resolution domain chosen is 50 E to 109 E and 4 S to 41 N and there are 101 grid points along a latitude circle and 120 points along the longitudinal direction.
