This report describes a research and development program conducted for the National Center for Atmospheric Research by the Minnesota Mining and Manufacturing Company, St. Paul,...

In this study, we present multisatellite observations of the large-scale structures of subauroral polarization streams (SAPS) during the main phase of a severe geomagnetic storm...

This paper presents a new CAPRAM–GECKO-A protocol for mechanism auto-generation of aqueous-phase organic processes. For the development, kinetic data in the literature were...

For the first time the global extent of a mid stratospheric new particle layer is addressed, using the National Center for Atmospheric Research Community Earth System Model,...

The Winter Fog Experiment (WiFEX) was an intensive field campaign conducted at Indira Gandhi International Airport (IGIA) Delhi, India, in the Indo-Gangetic Plain (IGP) during...

Riming within mixed-phase clouds can have a large impact on the prediction of clouds and precipitation within weather and climate models. The increase of ice particle fall speed...

Approximately 1700 Pg of soil carbon (C) are stored in the northern circumpolar permafrost zone, more than twice as much C than in the atmosphere. The overall amount, rate, and...

The migrating diurnal tide is one of the dominant dynamical features in the low latitudes of the Earth's mesosphere and lower thermosphere (MLT) region, representing the...

The Precipitation-Runoff Modeling System (PRMS), a distributed-parameter hydrologic model, has been applied to the conterminous US (CONUS). Parameter sensitivity analysis was...

In this case study, numerical simulations using the Weather Research and Forecasting model (WRF) are performed for 3-4 May 2002, in which two propagating rain episodes occurred...

Understanding changes in the burden and growth rate of atmospheric methane (CH4) has been the focus of several recent studies but still lacks scientific consensus. Here we...

An intercomparison of the distribution and extreme values of daily precipitation between the National Center for Atmospheric Research Community Climate System Model, version 4...

Vertical shears of horizontal winds play an important role in the dynamics of the upper atmosphere. Prior observations have indicated that these shears predominantly occur in...

Previous modeling work showed that aerosol can affect the position of the tropical rain belt, i.e., the intertropical convergence zone (ITCZ). Yet it remains unclear which...

The workshop provided a platform for the cloud modeling community to discuss the current issues, progress, and challenges based on the four cases. Each case was assigned a full...

Quantification of heat and constituent transport by gravity waves (GWs) in global models is challenging due to limited model resolutions. Current parameterization schemes suffer...

Context. Strong ultraviolet (UV) emission from the sun will be observed by the Lyman-alpha Solar Telescope (LST) on board the Advanced Space-based Solar Observatory (ASO-S),...

A 10-hour wave in the mesospheric and lower thermospheric neutral winds and temperature was observed at northern high-latitude stations Resolute (74.9degreesN) and Eureka...

This paper describes the results of a sea level measurement test conducted off La Jolla, California, in November of 1991. The purpose of this test was to determine accurate sea...

The severity of the double Intertropical Convergence Zone (DI) problem in climate models can be measured by a tropical precipitation asymmetry index (PAI), indicating whether...
