Large scale features and assessment of spatial scale correspondence between TMPA and IMD rainfall datasets over Indian landmass
TL;DR: In this article, daily rainfall datasets of 10 years (1998-2007) of TRMM Multi-satellite Precipitation Analysis (TMPA) version 6 and India Meteorological Department (IMD) gridded rain gauge have been compared over the Indian landmass, both in large and small spatial scales.
New spatial and temporal indices of Indian summer monsoon rainfall
Sanjeev Dwivedi,Sanjeev Dwivedi,R. Uma,T. V. Lakshmi Kumar,M. S. Narayanan,Samir Pokhrel,R. H. Kripalani +6 more
TL;DR: In this article, the authors proposed two new spatial and temporal indices for Indian southwest monsoon rainfall, which were calculated using the 115 years of IMD daily 0.25°× 0.75° gridded rainfall data and showed that the temporal indices have better link with circulation indices as compared to the new spatial indices.

Variability in MODIS NDVI in Relation to Southwest Monsoon over Western Ghats, India
T. V. Lakshmi Kumar,R. Uma,K. Koteswara Rao,Humberto Alves Barbosa,E. Prabha Jothi,K. V. K. R. K. Patnaik +5 more
TL;DR: In this article, the NDVI over Western Ghats (number of test sites are 16) showed increasing tendency and the pronounced changes in NDVI have been studied in the context of southwest monsoon's distribution and activity.
The role of El Niño Southern Oscillation on the patterns of cycling rates observed over India during the monsoon season
TL;DR: In this article, the trend and interannual variability of total integrated precipitable water vapor (PWV) have been studied over India for the period 1979-2004 using NCEP/National Centre for Atmospheric Research reanalysis data with 2.5° × 2° resolution, and the spatial pattern of temporal correlations of CR with SOI and Nino 3 SST displayed significant positive and negative values in peninsular and central Indian portions of India respectively.

Understanding convection features over Bay of Bengal using sea surface temperature and atmospheric variables
TL;DR: In this article, the authors have divided the Bay of Bengal into ten different subregions (SR) and have attempted to study the connection between the above-stated variables during convective and non-convective events in the southwest monsoon (SWM) season (June to September) for the period 1998-2010.
