Changes in the Westward Transport of Saharan Dust From West Africa With Anthropogenic Forcing in the WRF Model

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Large uncertainties exist for future westward Saharan dust transport with increasing Greenhouse Gas emissions. We evaluate future changes in westward dust transport at the longitude of 18.6°W and a latitude range of 4°N–30°N using the Weather Research and Forecasting Model (WRF) with the GOCART dust module for the present‐day, with ERA‐Interim

Validation and Comparison of Long-Term Accuracy and Stability of Global Reanalysis and Satellite Retrieval AOD

Remote Sensing
Reanalysis and satellite retrieval are two primary approaches for obtaining large-scale and long-term Aerosol Optical Depth (AOD) datasets. This study evaluates and compares the accuracy, long-term stability, and error characteristics of the MERRA-2 ...

Global Diurnal Precipitation Cycle in the AI Model GraphCast and a 5‐km Unified Model: Challenges and Opportunities

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract This study evaluates the ability of the AI weather forecast model GraphCast to reproduce the global diurnal cycle of boreal summer precipitation, comparing it with Integrated Multi‐satellite Retrievals for GPM (IMERG) satellite observations, the ERA5 reanalysis, and an experimental global 5‐km Met Office Unified Model (UM) which is convection ...

Global large-scale stratosphere–troposphere exchange in modern reanalyses [PDF]

Atmospheric Chemistry and Physics, 2017
Stratosphere–troposphere exchange (STE) has important impacts on the chemical and radiative properties of the upper troposphere and lower stratosphere. This study presents a 15-year climatology of global large-scale STE from four modern reanalyses: ERA ...

Prevalent Greening Conceals the Forgone Ecological Potential of Forest Loss in Southeast Asia

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Across Southeast Asia (SEA), rapid land‐use transformations have extensively replaced natural forests with fragmented plantations and agricultural mosaics. However, quantifying the ecological legacy of this transformation is hindered by persistent cloud cover and the confounding signal of vegetation growth driven by concurrent environmental ...

Comparative Evaluation of the Third-Generation Reanalysis Data for Wind Resource Assessment of the Southwestern Offshore in South Korea

Atmosphere, 2018
This study evaluated the applicability of long-term datasets among third-generation reanalysis data CFSR, ERA-Interim, MERRA, and MERRA-2 to determine which dataset is more suitable when performing wind resource assessment for the ‘Southwest 2.5 GW ...

River Discharge, Arctic Report Card: Update for 2011 [PDF]

, 2011
Total annual discharge, 1813 km3 /year, in 2010 from the six largest Eurasian rivers (Sev. Dvina, Pechora, Ob, Yenisey, Lena and Kolyma) flowing into the Arctic Ocean was very close to the 1936-2009 long-term mean of 1808 km3 /year. Mean annual discharge,

An Assessment of NASA’s GMAO MERRA-2 Reanalysis Surface Winds [PDF]

Journal of Climate, 2019
Abstract The quality of MERRA-2 surface wind fields was assessed by comparing them with 10 years of measurements from a wide range of surface wind observing platforms. This assessment includes a comparison of MERRA-2 global surface wind fields with the ones from its predecessor, MERRA, to assess if GMAO’s latest reanalyses improved the ...

Dust Decline Amplifies High‐Cloud Ice‐to‐Liquid Transition and Buffers the Radiative Feedback Under Warming

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract The response of the cloud phase to global warming is a critical yet poorly constrained component of Earth's climate sensitivity. While rising temperatures drive a thermodynamic transition from ice to liquid clouds, the role of ice‐nucleating particles in modulating this shift remains underexplored.

Heat engines and heat pumps in a hydrostatic atmosphere: How surface pressure and temperature constrain wind power output and circulation cell size

, 2016
The kinetic energy budget of the atmosphere's meridional circulation cells is analytically assessed. In the upper atmosphere kinetic energy generation grows with increasing surface temperature difference \$\Delta T_s\$ between the cold and warm ends of a
