Raindrop size distribution (DSD) retrieval from remote radar measurements or from in situ disdrometer measurements is an important area of research. If the shape (μ) and slope...

This report describes the structure and operation of the Coronal Dynamics (C/D) Project's data system. The instrument system, based on the island of Hawaii, has been fully...

There is a thin transition region (TR) in the solar atmosphere where the temperature rises from 10,000 K in the chromosphere to millions of degrees in the corona. Little is...

One of the well-known challenges of fog forecasting is the high spatio-temporal variability of fog. An ensemble forecast aims to capture this variability by representing the...

Air pollution simulations critically depend on the quality of the underlying meteorology. In phase 2 of the Air Quality Model Evaluation International Initiative (AQMEII-2),...

The seasonal and interannual variability of transport times from the northern midlatitude surface into the Southern Hemisphere is examined using simulations of three idealized...

This User's Guide describes the overall design of the most recent version of the NCAR Community Climate Model, CCM2. In addition to in-depth information about running the CCM2...

It has already been shown that the Thermosphere-Ionosphere-Electrodynamics General Circulation Model (TIE-GCM) is capable of reproducing the pre-reversal enhancement (PRE) of...

This article does not have an abstract or article summary.

The response of stratospheric climate and circulation to increasing amounts of greenhouse gases (GHGs) and ozone recovery in the twenty-first century is analyzed in simulations...

Catastrophic failures in the built and natural environment resulting from climate extremes such as flooding have become all too familiar. Limit state design under changing...

The Pacific Atmospheric Sulfur Experiment (PASE) was field mission that took place aboard the NCAR C-130 airborne laboratory over the equatorial Pacific Ocean near Christmas...

This study analyzes spatial and temporal characteristics of multiyear droughts and pluvials over the southwestern United States with a focus on the upper Colorado River basin....

The November event of the Madden-Julian oscillation (MJO) during the Dynamics of North Atlantic Models (DYNAMO) field campaign was simulated using the global compressible...

Decaying Hall magnetohydrodynamic (HMHD) turbulence is studied using three-dimensional (3D) direct numerical simulations with grids up to 768(3) points and two different types...

Transport pathways of air originating in the upper-tropospheric Asian monsoon anticyclone are investigated based on three-dimensional trajectories. The Asian monsoon anticyclone...

We derive an explicit expression for the coronal wind mass-loss rate in terms of either the surface field or the surface rotation rate. This result is based on a currently used...

We describe the primary observational features of solar cycles, as seen in the photosphere, and review progress made over the past sixty years to simulate and predict these...

High-latitude neutral winds often circulate in a two-cell pattern as driven by large-scale auroral forcing. However, auroral forcing also occurs in various types of mesoscale...

Ozone depletion potentials (ODPs) are an important metric in national and international policy for evaluating the relative importance of different gases to affecting...
