We are all familiar with the proverbial "100-year flood," a concept instrumental in engineering design for water resources management. This concept, generally termed a "return...

We collected surface snow samples from three different glaciers - Yala, Thana, and Sachin - in the central and western Himalayas to understand the spatial variability and...

This manual contains documentation for users of the NCAR Scientific Subroutine Library (NSSL) system file library called ULIB. It is published in three volumes. Each program...

This scientific assessment examines changes in three climate extremes—extratropical storms, winds, and waves—with an emphasis on U.S. coastal regions during the cold season....

The main objective of this study is to observationally constrain processes in tropical and midlatitude mesoscale convective systems (MCSs), and to use these constraints for...

The Daniel K. Inouye Solar Telescope (DKIST) advances studies of solar magnetism through high-precision and accuracy in polarimetry at frontier spatial and temporal scales. A...

The light-wind, clear-sky, very stable boundary layer (vSBL) is characterized by large values of bulk Richardson number. The light winds produce weak shear, turbulence, and...

This study isolates the influence of sea ice mean state on pre-industrial climate and transient 1850-2100 climate change within a fully coupled global model: The Community Earth...

A direct numerical simulation (DNS) of an unstably stratified convective boundary layer with system rotation was performed to study top-down and bottom-up diffusion processes....

A regional atmospheric inversion method has been developed to determine the spatial and temporal distribution of CO2 sinks and sources across New Zealand for 2011-2013. This...

We report on a new method to derive the on-orbit electron density using the Tri Global Navigation Satellite System (GNSS) Radio-occultation System (Tri-GNSS Radio occultation...

This paper presents a multiscale hybrid ensemble-variational (EnVar) data assimilation strategy with an hourly rapid update aiming to improve analysis of convection via radar...

The causes of the ionospheric annual asymmetry, which refers to a larger averaged electron density at geomagnetic conjugate latitudes in December than in June, remain an...

Structural and parametric problems associated with physical parameterizations are often tied together in weather and climate models. This study examines the sensitivities of...

Key developments have been made to the NCAR Whole Atmosphere Community Climate Model with thermosphere and ionosphere extension (WACCM-X). Among them, the most important are the...

Study region:The Yarlung Tsangpo Basin (YB) on the Tibetan Plateau. Study focus: Characteristics and changes of air temperature, precipitation, snow cover, snow depth, glacier,...

It is the purpose of this paper to propose a standard test case suite for two-dimensional transport schemes on the sphere intended to be used for model development and...

Deep convection in the Labrador Sea (LS) resumed in the winter of 2007/08 under a moderately positive North Atlantic Oscillation (NAO) state. This is in sharp contrast with the...

This technical note summarizes metrics that have been defined to assess the quality of forecasts of solar irradiance and solar power production forecasting. A set of six base...

Understanding the roles of land surface conditions and atmospheric circulation on continental daily tempera-ture variance is key to improving predictions of temperature...
