Research on Regional Climate Model (RegCM4)

The RIMES Seasonal Climate Division uses the Regional Climate Model (RegCM4) for dynamical downscaling of seasonal prediction on an experimental basis. Two experiments were carried out on extreme monsoon cases (large deficit rainfall in 2002 and normal rainfall year 2003) over India. The model was initialized on 1st May and integrated up to 31 October for 2002 and 2003. The results indicate that the model is well simulated to the monsoon features, such as rainfall intensity and distribution, and circulation features during the extreme monsoon seasons.
