Influence of dynamic and thermodynamic features on Indian summer monsoon
- Cochin Univ. of Science and Technology (India)
Indian summer monsoon plays vital role in the economy of the country. Being an agricultural country, the onset phase of monsoon is important since beginning of cultivation depends on rain-fed irrigation. Summer heating of the Asian land mass and subsequent differential heating between peninsular and north India are considered to be the principal cause for the summer monsoon. An east-west synoptic scale zonal circulation is observed over the Indian region during monsoon period which is similar to the planetary scale circulation. The ascending branch of this circulation is over northwest India and the descending branch is over the northeast India. This east-west zonal circulation is closely related to the monsoon activity. During the onset phase of monsoon spectacular changes occur in the dynamical and thermodynamic structure of the atmosphere. In this paper an attempt is made to diagnose the features of the atmosphere over the Indian region employing dynamical and thermodynamical parameters to as to bring out the relationship between structure of atmosphere and strength of monsoon. Preliminary results indicate that the strength of monsoon and its various epochs are influenced by dynamic and thermodynamic features of the atmosphere.
