We present a study of spectral laws for helical turbulence in the presence of solid body rotation up to Reynolds numbers Re ~ 1×10⁵ and down to Rossby numbers Ro ~...

The application of water isotopes to estimate the glacial-interglacial cycle of temperature (T) assumes the validity of the present-day spatial relationship between Ta and...

Idealized simulations of the 15 May 2009 squall line from VORTEX2 are evaluated in this study. Four different microphysical setups are used, with either single-moment (1M) or...

Wildland fire decision support systems require accurate predictions of wildland fire spread. Fuel moisture content (FMC) is one of the important parameters controlling the rate...

The INSPIRE project was dedicated to the study of physical processes and their effects in ionosphere which could be determined as earthquake precursors together with detailed...

Strong tropical cyclones often undergo eyewall replacement cycles that are accompanied by concentric eyewalls and/or rapid intensity changes while the secondary eyewall...

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....

Interaction between equatorially trapped disturbances and tropical convection is investigated using a nonhydrostatic global model that applies the cloud-resolving convection...

We present the frequency redistribution function for a polarized three-term atom of the Lambda-type in the collisionless regime, and we specialize it to the case where both the...

Motivated by numerous lower atmosphere climate model hindcast simulations, we performed simulations of the Earth's atmosphere from the surface up through the thermosphere-...

The retreat of Arctic sea ice in recent decades is a pre-eminent signal of climate change. What role has the atmospheric circulation played in driving the sea ice decline? To...

Paleoclimate reconstructions of the Early Eocene provide important data constraints on the climate and hydrologic cycle under extreme warm conditions. Available terrestrial...

The National Center for Atmospheric Research (NCAR) operated an Integrated Sounding System (ISS) in Miami, Florida, for the CPS (Clouds and Precipitation Study) in late summer...

Large volcanic eruptions drive significant climate perturbations through major anomalies in radiative fluxes and the resulting widespread cooling of the surface and upper ocean....

To investigate the response of the meteoric metal layers in the mesosphere and lower thermosphere regions to the 27-day solar rotational cycle, a long-term simulation of the...

We present a realistic numerical model of sunspot and active region formation based on the emergence of flux bundles generated in a solar convective dynamo. To this end, we use...

For atmospheric tides driven by solar heating, the database of climate model output used in the most recent assessment report of the Intergovernmental Panel on Climate Change...

Within the geoscience community, enthusiasm for the scientific Python ecosystem continues to grow (Nagpal and Gabrani 2019). As software tools created with Python continue to...

This technical note describes the Fortran code (version 1) of the PSU/NCAR mesoscale model (MM5). It is intended to provide a detailed documentation of the model code for users...

We present measurements of organic aerosol (OA) in urban plumes from Houston and Dallas/Fort Worth as well as in industrial plumes in the Houston area during TexAQS-2006....
