Northern hemisphere planetary waves are strong in the winter and weak in the summer, and they go through a fast transition around equinox. This transition is studied here using...

Ionospheric observations from the ground-based GPS receiver network, CHAMP and GRACE satellites and ionosondes were used to examine topside and bottomside ionospheric variations...

Variable-resolution global climate models (VRGCMs) are a dynamical downscaling method that can reach spatiotemporal scales needed for regional climate assessments. Over the...

The GEOstationary Coastal and Air Pollution Events (GEO-CAPE) Airborne Simulator (GCAS) was developed in support of NASA's decadal survey GEO-CAPE geostationary satellite...

In this paper, we present an overview of concepts and data concerning inverse cascades of excitation towards scales larger than the forcing scale in a variety of contexts, from...

Lagrangian transitions in mesoscale cellular convective (MCC) clouds beginning as closed cell MCC and transitioning to open cells or disorganized but cellular MCC are explored...

The authors examine the effect of seasonal crop development and growth on the warm- season mesoscale heat, moisture, and momentum fluxes over the central Great Plains region of...

A 30-year minimum Antarctic snowmelt record occurred during austral summer 2008-2009 according to spaceborne microwave observations for 1980-2009. Strong positive phases of both...

Long-term trends in the mesosphere, thermosphere, and ionosphere are areas of research of increasing importance both because they are sensitive indicators of climatic change and...

This study investigates the underlying atmospheric dynamics associated with intense dust storms in summer 2018 over the Arabian Peninsula (AP); a major dust source at global...

A parameterization for the subgrid-scale cloud and precipitation fractions has been incorporated into the Predicted Particle Properties (P3) microphysics scheme for use in...

Based on the observations from the balloon-borne instrument High-altitude Interferometer WIND experiment (HIWIND) and the simulations from the Thermosphere Ionosphere...

North American Monsoon (NAM) rainfall is a vital water resource in the United States Southwest, providing 60-80% of the region's annual precipitation. However, NAM rainfall is...

As part of the second phase of the spatial forecast verification intercomparison project (ICP), dubbed the Mesoscale Verification Intercomparison in Complex Terrain (MesoVICT)...

Sea salt aerosol (SSA) plays a significant role in the atmosphere through aerosol direct and indirect effects, and in atmospheric chemistry as a source of tropospheric bromine....

This atlas presents atmospheric general circulation statistics derived from twelve years (1979-1990) of daily National Meteorological Center (NMC) operational geopotential...

Hydrogen fluoride (HF) is often used as a simple reference for other column observations of chemically active stratospheric species. However, seasonal and shorter timescale...

The hydrological impact of enhancing Earth's albedo by solar radiation management is investigated using simulations from 12 Earth System models contributing to the...

The authors use a procedure called the method for object-based diagnostic evaluation, commonly referred to as MODE, to compare forecasts made from two models representing...

Trace chemical species have been used in numerical models to calculate the age of air (AOA), which is a measure of the strength of the mean meridional circulation. The trend in...
