Measurements of atmospheric CH₄ from air samples collected weekly at 46 remote surface sites show that, after a decade of near-zero growth, globally averaged atmospheric methane...

This study revisits the axisymmetric tropical cyclone (TC) theory from D. K. Lilly's unpublished manuscript (Lilly model) and compares it to axisymmetric TC simulations from a...

Automated easy-to-use tools capable of generating spatial-temporal weather scenarios for the present day or downscaled future climate projections are highly desirable. Such...

The Cooperative Program for Operational Meteorology, Education, and Training (COMET)'s mission when it began in 1990 was to deliver professional development opportunities to...

We compare two seemingly different methods of estimating random error statistics (uncertainties) of observations, the three-cornered hat (3CH) method and Desroziers method, and...

Climate change challenges conservation planners in making decisions about habitat site selection and augmentation. This pilot study explores the use of Robust Decision Making...

This study attempts to understand how surface heat fluxes in different storm regions affect tropical cyclone (TC) size. The Advanced Research version of the Weather Research and...

This symposium was held to celebrate Harry van Loon's contribution to Climate Studies. Harry van Loon has been a scientist at NCAR since 1963. Since that time he has published...

A recently developed cell-integrated semi-Lagrangian (CISL) semi-implicit nonhydrostatic atmospheric solver that uses the conservative semi-Lagrangian multitracer (CSLAM)...

The increased availability of radio occultation (RO) data offers the ability to detect and study turbulence in the Earth's atmosphere. An analysis of how RO data can be used to...

The North American Monsoon (NAM) system is an annual weather pattern that brings summer rains to the dry regions of the United States southwest and northwestern Mexico. Broader...

Gravity waves are one of the main drivers of atmospheric dynamics. The spatial resolution of most global atmospheric models, however, is too coarse to properly resolve the small...

Climate change scenario simulations with the Community Climate System Model version 3 (CCSM3), a global coupled climate model, show that if concentrations of all greenhouse...

Conversations with Bernhard Haurwitz.

Mesoscale organization of convection is typically not represented in global circulation models, and hence its influence on the global circulation is not accounted for. The...

Precipitation extremes will increase in a warming climate, but the response of flood magnitudes to heavier precipitation events is less clear. Historically, there is little...

Particulate matter with the diameter smaller than 2.5 mu m (PM2.5) poses health threats to human population. Regardless of efforts to regulate the pollution sources, it is...

This work presents an analysis of seasonal variations of medium-scale perturbations (similar to 500 to similar to 5,700 km) spanning altitudes from 90 to 250 km using...

In this paper, we present a case study of the radial interplanetary magnetic field (IMF B-x)-induced asymmetric solar wind-magnetosphere-ionosphere (SW-M-I) coupling between the...
