Abstract:
In recent years, the research on atmospheric gradient for weather forecasting as well as GPS positioning has significantly increased as it contains real atmospheric information. In this paper, the seasonal dependence of the atmospheric gradient orientation consistent with wind direction has been presented vividly. We have illustrated the gradient time series of four different monsoon seasons for the tropical station Singapore. The tropospheric gradient alters its direction from season to season and mostly remains oriented along the wind flow. Also, the cumulative distribution plot between the abrupt change in gradient and precipitation gives rise to an indicative feature for rainfall forecasting. The results substantiate the fact that gradient can be contemplated as an imperative atmospheric parameter for predicting a weather event for a larger region
