Context. Analyses of sunspot observations revealed a fundamental magnetic property of the umbral boundary: the invariance of the vertical component of the magnetic field.Aims....

Despite tectonic conditions and atmospheric CO2 levels (pCO(2)) similar to those of present-day, geological reconstructions from the mid-Pliocene (3.3-3.0 Ma) document high lake...

Reducing fatalities from tornadoes in the southeastern United States requires considering multiple societal factors, including the risk perceptions that influence how people...

A discontinuous Galerkin (DG) transport scheme is presented that employs the Yin-Yang grid on the sphere. The Yin-Yang grid is a quasi-uniform overset mesh comprising two...

Context. Large aperture ground-based solar telescopes allow the solar atmosphere to be resolved in unprecedented detail. However, ground-based observations are inherently...

Glacier mass loss is one of the main contributors to sea‐level rise and poses challenges for future water resources. Refining glacier projections and sources of...

Recent studies have focused on the role of cloud radiative effects (CRE) in governing the mean atmospheric circulation and its response to climate change. This study instead...

Based on a joint analysis of an ensemble mean of satellite sea surface salinity retrievals and the output of a high-resolution numerical ocean circulation simulation, physical...

Long-term (1967-2008) glass eel catches were used to investigate climatic effects on the annual recruitment of Japanese eel to Taiwan. Specifically, three prevailing hypotheses...

Carbon, the human's most reliable fuel type in the past, must be neutralized in this century toward the Paris Agreement temperature goals. Solar power is widely believed a key...

The effect of sea breeze circulation on stratification of the vertical formaldehyde (HCHO) concentration vertical profiles is explored using a regional atmospheric chemical...

In this study, multiple data sets from Beidou geostationary orbit satellites total electron contents (TECs), ionosonde, meteor radar, magnetometer, and model simulations have...

Anthropogenic increases of greenhouse gases warm the troposphere but have a cooling effect in the middle and upper atmosphere. The steady increase of CO₂ is the dominant cause...

A workshop on particulate models was held at NCAR in Boulder, Colorado on 21 August 1970 to create more realistic models of atmospheric particulates that are required for...

We present numerical simulations with the Whole Atmosphere Community Climate Model, eXtended version (WACCM-X), whose dynamics is constrained by atmospheric specifications...

Scenarios are key tools in analyses of global environmental change. Often they consist of quantitative and qualitative components, where the qualitative aspects are expressed in...

Over the last two decades, the important role of atmospheric rivers in many extreme precipitation and flood episodes in western North America, the western Pacific, Europe, New...

In this study the authors evaluate two algorithms, the so-called beta (β) and constrained methods, proposed for retrieving the governing parameters of the "normalized" gamma...

Extreme precipitation and temperature indices in reanalysis data and regional climate models are compared to station observations. The regional models represent most indices of...
