CLIMATE. 



Local conditions often radically affect the rainfall at 

 particular stations. Thus, Godda, situated in the lee of the 

 Rajmehal Hills in respect to the moist winds from the Bay 

 of Bengal, has a rainfall much below the average of the 

 northern Santal Parganas. Ghatsila, situated in eastern 

 Singbhum, in a belt where the same moist winds are first 

 forced to rise on striking the eastern Singbhum mountains, 

 has a heavier fall than Chaibassa situated to the west of 

 them. Apart from such purely local variations, tho heaviest 

 rainfall is seen to be in two well-defined regions. The one 

 embracing Jashpur, Sirguja, western Ranchi and western 

 Singbhum and Gangpur, is a region of extensive high forest, 

 as well as being nearest to the axis of minimum pressure 

 towards which the two branches of the monsoon converge 

 from the opposite coasts. 1 The other lies in the northern 

 Santal Parganas, a region which is exposed to the moist 

 breezes blowing up the Gangetic valley, and perhaps also to 

 the deflected monsoon winds which sweep the base of the 

 Himalayas.
