This study presents climate change results from the North American Regional Climate Change Assessment Program (NARCCAP) suite of dynamically downscaled simulations for the North...

Objective performance metrics that measure precipitation variability across time scales from subdaily to interannual are presented and applied to Historical simulations of...

The convective momentum transport (CMT) properties of 13 215 rainbands within a Madden-Julian oscillation (MJO) event simulated by a global nonhydrostatic model are examined....

Long-term trends in precipitable water (PW) are an important component of climate change assessments for the Tibetan Plateau (TP). PW products from Moderate Resolution Imaging...

Numerical models of supercell thunderstorms produce near-ground rotation about a vertical axis (i.e., vertical vorticity) after the development of rain-cooled outflows and...

Peroxyacetyl nitrate (PAN) is an important trace gas that serves to transport nitrogen oxide radicals throughout the troposphere. We present an analysis of satellite...

This report is part of a series prepared for the Materials Research Project of the NCAR Scientific Balloon Facility in order to extend the reliability and capabilities of...

Polar cap ionospheric plasma flow studies often focus on large-scale averaged properties and neglect the mesoscale component. However, recent studies have shown that mesoscale...

In order to make a worldwide analysis of the current system of the lunar daily geomagnetic variation, the geomagnetic data collected during the IGY/IGC period (July 1957 to...

An observed turbulence encounter that occurred outside a mesoscale convective system over the central United States on 3 June 2005 is investigated using observations and high-...

CLUBB (Cloud Layers Unified by Binormals) is a higher-order closure (HOC) method with an assumed joint probability density function (PDF) for the subgrid variations in vertical...

Particle energies and fluxes have predominantly been measured from instruments onboard satellites. In this study, we use daytime ground-based oxygen redline emission...

We describe the Geophysical Fluid Dynamics Laboratory's CM4.0 physical climate model, with emphasis on those aspects that may be of particular importance to users of this model...

We present results of an investigation aimed at characterizing the effects of oceanic impacts of 500 m and 1 km diameter asteroids on the lower and middle atmosphere, estimating...

Understanding the historical and future response of the global climate system to anthropogenic emissions of radiatively active atmospheric constituents has become a timely and...

Recent flooding related to extreme precipitation in the UK has highlighted the importance of better understanding these events. Many studies have quantified annual exceedance...

This paper provides an assessment of Article 4.1 of the Paris Agreement on climate; the main goal of which is to provide guidance on how "to achieve the long-term temperature...

This report discusses teleconnection in the atmosphere and extends the analysis to the stratosphere. The intent of this document is to provide a more comprehensive view of...

This report is a further investigation of wind measurement errors using the 13.6 kHz Omega signals, and is based on assumptions that are either "reasonable" or cautious enough...

Global quantitative precipitation estimates (QPEs) at higher spatial and temporal resolutions are critical for the development of applications that address a variety of...
