Overview

What is he best known for?

The fields of study he is best known for:

  • Ecology
  • Carbon dioxide
  • Oceanography

Rengaswamy Ramesh mainly investigates Monsoon, Quaternary, δ18O, Geochemistry and Holocene. In the field of Climatology and Oceanography he studies Monsoon. His Quaternary research includes elements of Caliche, East Asian Monsoon and Last Glacial Maximum.

His δ18O research includes themes of Atmospheric sciences, δ13C, Hydrology, Altitude and Dendrochronology. His Holocene study combines topics from a wide range of disciplines, such as Structural basin, Desert climate, Pleistocene and Precipitation. His Paleoclimatology research incorporates elements of Foraminifera and Physical geography.

His most cited work include:

  • The Physical Science Basis (3670 citations)
  • High-Resolution Holocene Environmental Changes in the Thar Desert, Northwestern India (337 citations)
  • Information from paleoclimate archives (259 citations)

What are the main themes of his work throughout his whole career to date?

The scientist’s investigation covers issues in Monsoon, Oceanography, Climatology, δ18O and Holocene. The Monsoon study combines topics in areas such as Last Glacial Maximum, Paleoclimatology, Isotopes of oxygen and Precipitation. His Quaternary research extends to Last Glacial Maximum, which is thematically connected.

His work deals with themes such as Nitrate and New production, which intersect with Oceanography. His studies in Climatology integrate themes in fields like Speleothem, Dendrochronology, Climate change and Stalagmite. His work in δ18O tackles topics such as Atmospheric sciences which are related to areas like Relative humidity, Growing season and Isotopes of carbon.

He most often published in these fields:

  • Monsoon (41.92%)
  • Oceanography (35.86%)
  • Climatology (32.32%)

What were the highlights of his more recent work (between 2017-2021)?

  • Monsoon (41.92%)
  • Climatology (32.32%)
  • δ18O (31.31%)

In recent papers he was focusing on the following fields of study:

His primary scientific interests are in Monsoon, Climatology, δ18O, Indian summer monsoon and Oceanography. His study in Monsoon is interdisciplinary in nature, drawing from both Speleothem, Holocene, Vegetation, Physical geography and Isotopes of oxygen. His research in the fields of Last Glacial Maximum overlaps with other disciplines such as Spatial variability.

His Climatology research focuses on subjects like Stalagmite, which are linked to Global warming, East Asian Monsoon, Paleoclimate Modelling Intercomparison Project and Southern Hemisphere. His research in δ18O intersects with topics in Bay, Tropics, Atmospheric sciences, Precipitation and Chronology. In the subject of general Oceanography, his work in Bloom is often linked to High rate, thereby combining diverse domains of study.

Between 2017 and 2021, his most popular works were:

  • The Effect of Monsoon Circulation on the Stable Isotopic Composition of Rainfall (14 citations)
  • The Effect of Monsoon Circulation on the Stable Isotopic Composition of Rainfall (14 citations)
  • The Effect of Monsoon Circulation on the Stable Isotopic Composition of Rainfall (14 citations)

In his most recent research, the most cited papers focused on:

  • Ecology
  • Carbon dioxide
  • Oceanography

Rengaswamy Ramesh focuses on Climatology, Atmospheric sciences, Stalagmite, Monsoon circulation and Isotopic composition. His Climatology research is multidisciplinary, relying on both Speleothem, Climate change and δ18O. His Atmospheric sciences study integrates concerns from other disciplines, such as Wet season, Tropics, Precipitation, Water vapor and Moisture.

His research integrates issues of East Asian Monsoon, Monsoon, Paleoclimatology, Seasonality and Atmospheric circulation in his study of Stalagmite. His Monsoon research is multidisciplinary, relying on both Cave, Holocene, Global warming, Radiative forcing and Isotopes of oxygen. Rengaswamy Ramesh combines subjects such as Solar variation, Period, Teleconnection and Before Present with his study of Indian summer monsoon.
