The new regional 15-km Arctic System Reanalysis, version 2, provides the accuracy and details necessary for many Arctic climate studies over the period 2000-12.

We use observations from the 2015 Wintertime Investigation of Transport, Emissions, and Reactivity (WINTER) aircraft campaign to constrain the proposed mechanism of Cl-2...

This study revisits the axisymmetric tropical cyclone (TC) theory from D. K. Lilly's unpublished manuscript (Lilly model) and compares it to axisymmetric TC simulations from a...

During a 6-day intensive observing period in January 2021, Atmospheric River Reconnaissance (AR Recon) aircraft sampled a series of atmospheric rivers (ARs) over the...

Integrated water vapor (IWV) estimates derived from four different Special Sensor Microwave Imager (SSM/I) algorithms are collocated and compared with IWV retrievals using...

A comparative analysis between observational data from McMurdo Station, Antarctica and the Community Atmosphere Model version 6 (CAM6) simulation is performed focusing on cloud...

This study estimates the random error variances and standard deviations (STDs) for four datasets: Global Hawk (GH) dropsondes (DROP), the High-Altitude Monolithic Microwave...

An analysis of the influence and sensitivity of moisture in an idealized two-dimensional moist semigeostrophic frontogenesis model is presented. A comparison between a dry...

The South Asian summer monsoon is associated with a large-scale anticyclonic circulation in the upper troposphere and lower stratosphere (UTLS), which confines the air mass...

Recent advancements in artificial intelligence (AI) numerical weather prediction (NWP) have transformed atmospheric modeling. AI NWP models outperform state-of-the-art...

The development of human civilizations has occurred at a time of stable climate. This climate stability is now threatened by human activity. The rising global climate risk...

The importance of multivariate forecast error correlations between specific humidity, temperature, and surface pressure in perfect model assimilations of Global Positioning...

A positive-definite transport scheme for moisture is tested in a nonhydrostatic forecast model using convection-permitting resolutions. Use of the positive-definite scheme is...

One of the most important dynamical processes in the tropical stratosphere is the quasi-biennial oscillation (QBO) of the zonal wind. Still, the QBO is not well represented in...

The effects of breaking waves on near-surface wind turbulence and drag coefficient are investigated using large-eddy simulation. The impact of intermittent and transient wave...

This report contains the results of workshop participants who prioritized research and observational opportunities to achieve pre-landfall track forecast gains of this track-...

Detection and attribution (D&A) simulations were important components of CMIP5 and underpinned the climate change detection and attribution assessments of the Fifth...

In the original Predicted Particle Properties (P3) bulk microphysics scheme, all ice-phase hydrometeors are represented by one or more "free" ice categories, where the physical...

From 17-22 August 2017 simultaneous enhancements of ammonia (NH3), carbon monoxide(CO), hydrogen cyanide (HCN), and ethane (C2H6) were detected from ground-based solar...

This paper presents a detailed laboratory characterization of a thermal dissociation chemical ionization mass spectrometer (TD-CIMS) for the atmospheric measurement of...
