Toward a mechanistic modeling of nitrogen limitation on vegetation dynamics
Nitrogen is a dominant regulator of vegetation dynamics, net primary production, and terrestrial carbon cycles; however, most ecosystem models use a rather simplistic...- publication PDF

Separating emission and meteorological drivers of mid‐21st‐century air qualit...
Many Indian metropolitan areas currently suffer from severe air pollution such as PM2.5, which might continue into future decades, dependent on the trends in emission growth and...- publication PDF

Numerical investigation of the quasi 2 day wave in the mesosphere and lower t...
The zonal wave number 3 planetary wave with about a 2 day period is a recurrent wave feature in the mesosphere and lower thermosphere (MLT). The quasi 2 day wave (QTDW) exhibits...- publication PDF

Modeled and observed multidecadal variability in the North Atlantic jet strea...
Multidecadal variability in the North Atlantic jet stream in general circulation models (GCMs) is compared with that in reanalysis products of the twentieth century. It is found...- publication PDF

Frictionally induced feedback in a reduced dynamical model of tropical cyclon...
This study examines the role of frictional feedback in the atmospheric boundary layer during tropical cyclone (TC) development. Using a reduced model of TC dynamics, it is shown...- publication PDF

Momentum balance and gravity wave forcing in the mesosphere and lower thermos...
Gravity wave forcing (GWF), which is the primary driver of the mesospheric and lower thermospheric (MLT) circulation, is difficult to measure directly. In this work, the zonal...- publication PDF
