             abstract = "The Indian summer monsoon season of 2014 was erratic and ended up 
                         with a seasonal rainfall defcit of 12 % and a record drought in 
                         June. In this study we analyze the moisture transport 
                         characteristics for the monsoon season of 2014 using both NCEP FNL 
                         reanalysis (FNL) and CFSv2 (CFS) model data. In FNL, in June 2014 
                         there was a large area of divergence of moisture fux. In other 
                         months also there was lesser fux. This probably is the cause of 
                         2014 drought. The CFS model overestimated the drought and it 
                         reproduces poorly the observed rainfall over central India 
                         (65E95E; 5N35N). The correlation coeffcient (CC) between the IMD 
                         observed rainfall and CFS model rainfall is only 0.1 while the CC 
                         between rainfall and moisture fux convergence in CFS model is only 
                         0.20 and with FNL data \−0.78. This clearly shows that the 
                         CFS model has serious diffculty in reproducing the moisture fux 
                         convergence and rainfall. We found that the rainfall variations 
                         are strongly related to the moisture convergence or divergence. 
                         The hypothesis of Krishnamurti et al. (J Atmos Sci 67:34233441, 
                         2010) namely the intrusion of west African desert air and the 
                         associated low convective available potential energy inhibiting 
                         convection and rainfall shows some promise to explain dry spells 
                         in Indian summer monsoon. However, the rainfall or lack of it is 
                         mainly explained by convergence or divergence of moisture fux.",
