Modeling of Temperature and Rainfall of West Bengal through Remote Sensing and GIS Techniques

要旨

This study proposes an empirical methodology for modeling and mapping of the seasonal air temperature and annual rainfall using remote sensing and GIS techniques. The study area is Gangetic West Bengal in the eastern India, where a number of weather systems occur throughout the year. Gangetic West Bengal is a region of strong heterogeneous surface with several weather disturbances. The land use/land cover, soil texture and digital elevation model are used as the independent variables for temperature modeling. Rainfall modeling is done using humidity, cloud cover, land use /land cover and relief of the study area. Standard deviation errors are evaluated after comparing the predicted and observed value of temperature and rainfall using real station observations of the area. Prediction of mean temperature for monsoon season is better than winter season. For better improvement distance from the coastline and seasonal wind pattern are stressed to be included as independent variables.
