Atmospheric conservation properties in ERA‐Interim

Quarterly Journal of the Royal Meteorological Society, 2011
AbstractWe study the global atmospheric budgets of mass, moisture, energy and angular momentum in the latest reanalysis from the European Centre for Medium‐Range Weather Forecasts (ECMWF), ERA‐Interim, for the period 1989–2008 and compare with ERA‐40. Most of the measures we use indicate that the ERA‐Interim reanalysis is superior in quality to ERA‐40.

Arctic warming in ERA‐Interim and other analyses

Quarterly Journal of the Royal Meteorological Society, 2014
Near‐surface and lower‐tropospheric warming of the Arctic over the past 35 years is examined for several datasets. The new estimate for the near surface reported by Cowtan and Way in 2014 agrees reasonably well with the ERA‐Interim reanalysis for this region.

Comparison of VOS and ERA-Interim Wave Data

Volume 3: Structures, Safety, and Reliability, 2019
Abstract Accuracy of Voluntary Observing Ship’s reports is evaluated by a one-to-one comparison with ERA-interim database, specifically considering significant wave height. A first screening allows to detect the most common and undeniable mistakes, as for instance clear errors in reporting the position of the vessel, and delete these ...

Climatology of the ITCZ derived from ERA Interim reanalyses

Journal of Geophysical Research, 2011
The intertropical convergence zone (ITCZ) is usually analyzed in terms of the precipitation field. This study presents a new climatology of the ITCZ based on winds from ERA Interim reanalyses for the period 1990–2009. The central latitude of the ITCZ is defined as the zero crossing of the meridional wind averaged over 10 model levels below 900 hPa ...

Evaluation of ERA-Interim and MERRA Cloudiness in the Southern Ocean

Journal of Climate, 2014
Abstract The Southern Ocean cloud cover modeled by the Interim ECMWF Re-Analysis (ERA-Interim) and Modern-Era Retrospective Analysis for Research and Applications (MERRA) reanalyses are compared against Moderate Resolution Imaging Spectroradiometer (MODIS) and Multiangle Imaging Spectroradiometer (MISR) observations.

Determination of ERA-INTERIM Proficiency for Rainfall–Runoff Modeling

2020
In case of ungauged or poorly gauged basins, such as data-scarce Beas River basin, the main challenge is determining the utility of reanalysis data for simulation of river discharge. According to the researchers, the availability of large number of rain gauge station can improve the result of rainfall–runoff models.

The world ocean wave fields discerned from ERA-Interim spectra

Journal of Geophysical Research: Oceans, 2022
AbstractA wave field is a spatial expanse of the ocean surface in which waves of a single meteorological event are generated and propagate until their energy dissipates and disperses to the point where they are not detectable any further. Since water as a transport medium allows the superposition of waves of different sizes traveling in different ...

WRF high resolution dynamical downscaling of ERA-Interim for Portugal

Climate Dynamics, 2012
This study proposes a dynamically downscaled climatology of Portugal, produced by a high resolution (9 km) WRF simulation, forced by 20 years of ERA-Interim reanalysis (1989–2008), nested in an intermediate domain with 27 km of resolution. The Portuguese mainland is characterized by large precipitation gradients, with observed mean annual precipitation

Tropopause folds in ERA‐Interim: Global climatology and relation to extreme weather events

Journal of Geophysical Research: Atmospheres, 2015
AbstractTropopause folds are intimately linked to upper level frontogenesis and jet stream dynamics. They play an important role for stratosphere‐troposphere exchange, the dynamical coupling of upper and lower tropospheric levels, and for generating severe weather events.
