Overview

What is he best known for?

The fields of study he is best known for:

  • Meteorology
  • Statistics
  • Climate change

Gregory J. Hakim mainly investigates Climatology, Meteorology, Ensemble Kalman filter, Cyclogenesis and Potential vorticity. Gregory J. Hakim interconnects Storm, Geopotential height and Paleoclimatology in the investigation of issues within Climatology. His biological study spans a wide range of topics, including Climate system and Mean radiant temperature.

His Data assimilation and Forecast verification study in the realm of Meteorology interacts with subjects such as Environmental science. His Ensemble forecasting research integrates issues from Kalman filter, Statistical hypothesis testing, Covariance and Applied mathematics. His Anticyclone study combines topics in areas such as Mechanics, Surge and Mesoscale meteorology.

His most cited work include:

  • Boundary Conditions for Limited-Area Ensemble Kalman Filters (171 citations)
  • Ensemble-Based Sensitivity Analysis (137 citations)
  • Comparing Adjoint- and Ensemble-Sensitivity Analysis with Applications to Observation Targeting (135 citations)

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

His main research concerns Climatology, Environmental science, Data assimilation, Meteorology and Paleoclimatology. His Climatology research includes elements of Climate model and Atmospheric sciences. His Data assimilation study which covers Global change that intersects with Cryosphere and Physical geography.

His Meteorology research incorporates themes from Kalman filter and Covariance. His Paleoclimatology course of study focuses on Proxy and Northern Hemisphere and Geopotential height. Within one scientific family, Gregory J. Hakim focuses on topics pertaining to Potential vorticity under Tropopause, and may sometimes address concerns connected to Baroclinity and Jet stream.

He most often published in these fields:

  • Climatology (55.63%)
  • Environmental science (33.80%)
  • Data assimilation (30.99%)

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

  • Climatology (55.63%)
  • Environmental science (33.80%)
  • Data assimilation (30.99%)

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

The scientist’s investigation covers issues in Climatology, Environmental science, Data assimilation, Paleoclimatology and Global change. The study incorporates disciplines such as Climate model, Arctic, Radiative forcing, Climate system and Last Glacial Maximum in addition to Climatology. Throughout his Environmental science studies, Gregory J. Hakim incorporates elements of other sciences such as Climate sensitivity, Network planning and design, Surface, Meteorology and Ice core.

His Meteorology study frequently intersects with other fields, such as Kinetic energy. His Data assimilation research is multidisciplinary, incorporating elements of Atmosphere, Precipitation, Coral, Atmospheric circulation and Paleoceanography. His work investigates the relationship between Paleoclimatology and topics such as Proxy that intersect with problems in Linear regression.

Between 2017 and 2021, his most popular works were:

  • Consistent multi-decadal variability in global temperature reconstructions and simulations over the Common Era. (73 citations)
  • Last Millennium Reanalysis with an expanded proxy database and seasonal proxy modeling (43 citations)
  • Glacial cooling and climate sensitivity revisited. (25 citations)

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

  • Statistics
  • Meteorology
  • Climate change

His primary areas of investigation include Climatology, Paleoclimatology, Environmental science, Data assimilation and Climate model. Gregory J. Hakim works mostly in the field of Climatology, limiting it down to topics relating to Climate system and, in certain cases, Perturbation. His research in Paleoclimatology intersects with topics in Univariate, Proxy and Multi proxy.

His research integrates issues of Common spatial pattern and Ice sheet in his study of Proxy. His Data assimilation study integrates concerns from other disciplines, such as Arctic ice pack, Sea ice, Arctic and Albedo. He combines subjects such as Climate dynamics and Orbital forcing with his study of Climate model.
