Many multidecadal atmospheric reanalysis products are available now, but their consistencies and reliability are far from perfect. In this study, atmospheric precipitable water...

Vortex dipoles provide a simple representation of localized atmospheric jets. Numerical simulations of a synoptic-scale dipole in surface potential temperature are considered in...

A 1991 Study on Observational Systems discussed the need for universities to produce graduates capable of developing the next generation of observing systems and interpreting...

The dominantmode of seasonal variability in the global tropical upper-stratosphere and mesosphere zonalwind is the semiannual oscillation (SAO). However, it is notoriously...

Global navigation satellite system (GNSS) radio occultation (RO) receivers onboard the recently-launched COSMIC-2 (C2) satellite constellation provide an unprecedented number of...

The East Asian summer monsoon (EASM) circulation and summer rainfall over East China have experienced large decadal changes during the latter half of the 20th century. To...

In this study, two different particle models describing the structure and electromagnetic properties of snow are developed and evaluated for potential use in satellite combined...

The Climate Project at the National Center for Atmospheric Research held a symposium on analysis and modeling of climate on large spatial scales from 29 November to 2 December...

A community diagnostics and performance metrics tool for the evaluation of Earth system models (ESMs) has been developed that allows for routine comparison of single or multiple...

As well as strong upward propagation of planetary waves from the troposphere, the state of the stratospheric mean flow has been recognized as a key factor for the occurrence of...

We demonstrate that identification of stratospheric ozone changes attributable to ozone depleting substances and actions taken under the Montreal Protocol requires evaluation of...

Simple rate equation models for subfilter-scale scalar and momentum fluxes have previously been developed for application in the so-called "terra incognita" of atmospheric...

The Fe XIII 10747 and 10798 Ã lines observed in the solar corona are sensitive to the coronal magnetic field in such a way that, in principle, the full vector field at a point...

Ground-based observations show that persistent liquid-containing Arctic clouds occur frequently and have a dominant influence on Arctic surface radiative fluxes. Yet, without a...

Observations from the Horizontal Array Turbulence Study (HATS) field program are used to examine the attenuation of measured scalar fluxes caused by spatial separation between...

Flood forecasting in mountain basins remains a challenge given the difficulty in accurately predicting rainfall and in representing hydrologic processes in complex terrain. This...

The mid-Pliocene warm period (3.264-3.025 Ma) is the most recent geological period during which atmospheric CO2 levels were similar to recent historical values (similar to 400...

We use seeing-free high spatial resolution Ca II H data obtained by the SUNRISE observatory to determine properties of slender fibrils in the lower solar chromosphere. In this...

We investigate the role of moisture transport and recycling in characterizing two recent drought events in Texas (2011) and the Upper Midwest (2012) by analyzing the...

The 2023 World Climate Research Programme (WCRP) Open Science Conference underscored the critical need for increased climate change mitigation and adaptation efforts, along with...
