What is he best known for?
The fields of study he is best known for:
- Climatology
- Meteorology
- Climate change
His scientific interests lie mostly in Climatology, Atmospheric circulation, Troposphere, Precipitation and Sea surface temperature.
Sumant Nigam combines subjects such as Pacific ocean and Oceanography with his study of Climatology.
His work in Atmospheric circulation addresses issues such as Climate model, which are connected to fields such as HadCM3 and Global change.
His research on Troposphere concerns the broader Atmospheric sciences.
His biological study spans a wide range of topics, including Convection, Mass flux, Boundary layer, Pressure gradient and Tropical instability waves.
His research integrates issues of Warm season and Monsoon in his study of Precipitation.
His most cited work include:
- On the role of sea surface temperature gradients in forcing low-level winds and convergence in the tropics (1084 citations)
- ENSO, Pacific Decadal Variability, and U.S. Summertime Precipitation, Drought, and Stream Flow (366 citations)
- The North Pacific Oscillation–West Pacific Teleconnection Pattern: Mature-Phase Structure and Winter Impacts (279 citations)
What are the main themes of his work throughout his whole career to date?
His main research concerns Climatology, Precipitation, Atmospheric sciences, Sea surface temperature and Monsoon.
His Climatology study frequently draws connections to other fields, such as Climate model.
His study on Hydrometeorology is often connected to Shortwave radiation, Water balance and Context as part of broader study in Precipitation.
His work carried out in the field of Atmospheric sciences brings together such families of science as Vorticity, Teleconnection and Latitude.
The concepts of his Sea surface temperature study are interwoven with issues in Secular variation, Empirical orthogonal functions and Convection.
His study in Monsoon is interdisciplinary in nature, drawing from both Planetary boundary layer, Orography, Vegetation and Aerosol.
He most often published in these fields:
- Climatology (86.87%)
- Precipitation (31.31%)
- Atmospheric sciences (21.21%)
What were the highlights of his more recent work (between 2016-2021)?
- Climatology (86.87%)
- Seasonality (5.05%)
- El Niño Southern Oscillation (15.15%)
In recent papers he was focusing on the following fields of study:
His primary areas of study are Climatology, Seasonality, El Niño Southern Oscillation, Precipitation and Climate change.
When carried out as part of a general Climatology research project, his work on Sea surface temperature and Atlantic multidecadal oscillation is frequently linked to work in Observational analysis and Context, therefore connecting diverse disciplines of study.
In the field of Sea surface temperature, his study on Pacific decadal oscillation overlaps with subjects such as Pacific basin.
The Atlantic multidecadal oscillation study combines topics in areas such as Gulf Stream, Zonal and meridional and Ocean gyre.
Sumant Nigam undertakes interdisciplinary study in the fields of Precipitation and Basin modelling through his works.
His Climate model study combines topics in areas such as Hadley cell, Warm season and Surface air temperature.
Between 2016 and 2021, his most popular works were:
- Twentieth-Century Climate Change over Africa: Seasonal Hydroclimate Trends and Sahara Desert Expansion (45 citations)
- Gulf Stream Excursions and Sectional Detachments Generate the Decadal Pulses in the Atlantic Multidecadal Oscillation (21 citations)
- Recent subsurface North Atlantic cooling trend in context of Atlantic decadal-to-multidecadal variability (10 citations)
