Anomalies of net radiation during southwest monsoon over the Bay of Bengal

G.R.L. Rao, Y. VeenaDevi


Fifteen years of data are used for obtaining the insolation under cloud conditions using the incoming Solar radiation values given by Budyko for clear sky conditions. Taking into account the effective outgoing radiation, the net radiation is estimated over the Bay of Bengal. The fluctuations of net radiation anomalies during different monsoonal conditions are investigated. Negative anomalies of net radiation of more than 40 w/m2 are observed during the good monsoon year and positive anomalies of 20 w/m2 during poor monsoon year. For the purpose of individual case study two synoptic disturbances with different intensities were selected and the behaviour of the anomalies studied
