Global Energy and Water Budgets in MERRA [PDF]
Journal of Climate, 2011 Abstract Reanalyses, retrospectively analyzing observations over climatological time scales, represent a merger between satellite observations and models to provide globally continuous data and have improved over several generations. Balancing the earth’s global water and energy budgets has been a focus of research for more than two ...

An intercomparison of subtropical cut-off lows in the Southern Hemisphere using recent reanalyses: ERA-Interim, NCEP-CFRS, MERRA-2, JRA-55, and JRA-25 [PDF]
, 2020 Four recent reanalysis products ERA-Interim, NCEP-CFSR, MERRA-2 and JRA-55 are evaluated and compared to an older reanalysis JRA-25, to quantify their confidence in representing Cut-off lows (COLs) in the Southern Hemisphere.

A Global Climatology of Tropopause Folds in CAMS and MERRA‐2 Reanalyses [PDF]
Journal of Geophysical Research: Atmospheres, 2021 AbstractTropopause folds are the main mechanism underlying stratosphere‐to‐troposphere transport and influence tropospheric composition and weather systems by triggering convection. Here, we present the global climatology of tropopause folds in Copernicus Atmosphere Monitoring Service (CAMS) and Modern‐Era Retrospective analysis for Research and ...

Evaluation of four global reanalysis products using in-situ observations in the Amundsen Sea Embayment, Antarctica [PDF]
, 2016 The glaciers within the Amundsen Sea Embayment (ASE), West Antarctica, are amongst the most rapidly retreating in Antarctica. Meteorological reanalysis products are widely used to help understand and simulate the processes causing this retreat.

Compensation between Resolved and Unresolved Wave Drag in the Stratospheric Final Warmings of the Southern Hemisphere [PDF]
, 2015 The role of planetary wave drag and gravity wave drag in the breakdown of the stratospheric polar vortex and its associated final warming in the Southern hemisphere is examined using MERRA reanalyses, and a middle atmosphere dynamical model. The focus of
