Research interests: 

I study the processes that drive precipitation variability across Eurasia across a broad range of timescales, from the diurnal cycle to climate change. I have worked extensively on the diurnal precipitation cycle, low-pressure systems, and intraseasonal oscillations, and the interplay among them around South Asia, helping to improve understanding of these processes that provide water resources to billions of people and contribute to S2S prediction. I use in-situ observational data, atmospheric reanalysis and satellite remote sensing data to uncover important processes. I have recently studied the mechanism of nocturnal precipitation in the Meghalaya Plateau and the Himalayas, including glacierized areas.

Research topics:

• Diurnal cycles (DC) in cloud/precipitation systems: building blocks that form the hydrological cycle over land

Tibetan Plateau: the elevated heating system

The Himalayas including the glacierized area: headwaters of major rivers

The Meghalaya Plateau: nocturnal precipitation in the heaviest rainfall area in the world

 The Indochina Peninsula: importance of regional-scale mountain ranges

 The Maritime Continent: remarkable DC under ISOs

• Low pressure systems (LPSs):

Monsoon depressions over the Bay of Bengal:

 Effects of latent heating from the ocean surface and MCSs on the rapid development of the monsoon depressions

 Mechanism responsible for extreme rainfall event over the Himalayas

LPSs over monsoon trough: Effects of LPSs on interannual variation of summer total precipitation and extreme flood events

• Intraseasonal oscillations (ISOs):

Boreal summer intraseasonal oscillation(BSISO)

Roles of BSISO in the occurrence frequency of tropical cyclones and monsoon lows/depressions

Quasi-biweekly/ submonthly oscillation:

 Dominant submonthly oscillation in rainfall/convection in the Tibetan Plateau and Bangladesh region

 Modulation of DC by submonthly-scale ISO

Effects of quasi-stationary waves along the Asian jet on the Meiyu/Baiu activities

• Seasonal variation (SV):

Convective activity over the Tibetan Plateau throughout the year

• Interannual variation (IAV):

Effects of ISOs on the IAV of summer rainfall around Bangladesh region

 Effects of TDs on the IAV of summer rainfall around the Indochina Peninsula

 Dominant mode of IAV in precipitation over eastern Siberia

• Interdecadal variation and long-term trend:

 Long-term change in the onset of Asian monsoon region

 Long-term change in hydroclimate in eastern Siberia

 Interdecadal modulation of the ISOs over South Asia
