We demonstrate that the global cooling resulting from a range of nuclear conflict scenarios would temporarily increase the pH in the surface ocean by up to 0.06 units over a...

A group under Dr. Luis Alvarez at the Space Sciences Laboratory, University of California, is preparing a balloon-borne particle physics experiment, designed for recovery at...

This paper discusses large-scale climate variability for several marine ecosystems and suggests types of ecosystem responses to climate change. Our analysis of observations and...

The NCAR Whole Atmosphere Community Climate Model, with a quasi-uniform horizontal resolution of similar to 25 km and a vertical resolution of 0.1 scale height, produces large...

The effects of the tropical Pacific El Niño Southern Oscillation (ENSO) phenomenon are communicated to the rest of the globe via atmospheric teleconnections. Traditionally,...

Ensemble simulations are run with a global coupled climate model employing five forcing agents that influence the time evolution of globally averaged surface air temperature...

Motivated by observed anomalous features in cycle 23, as inferred from records of photospheric magnetic flux, we develop a flux transport dynamo-based scheme in order to...

Calibration of instrumental polarization is critical for measuring polarized radio emissions from astrophysical sources to extract the magnetic field information in...

Report on a complete theory development that gives an exact calculation for all angles with irrotational flow around a sphere, the easiest shape for a nose radome which includes...

The derivation of the meridional momentum flux arising from a multiscale horizontal velocity field in the intraseasonal, planetary, equatorial synoptic-scale dynamics (IPESD)...

We compare simulations from three high-top (with upper lid above 120 km) and five medium-top (with upper lid around 80km) atmospheric models with observations of odd nitrogen...

Turbulence parameterization plays a critical role in the simulation of many weather regimes. For challenging cases such as the stratocumulus-capped boundary layer (SCBL),...

A nascent in situ cirrus was observed on January 11, 2019 in the tropical tropopause layer (TTL) over the southwestern Indian Ocean, with the use of balloon-borne instruments....

The SCD computing system is complex, and it is difficult to disguise that complexity without impairing function. The IBM 4341 system is flexible; it is possible therefore to...

Midlatitude cirrus cloud radiative forcing (CRF) values at the tropopause over China are estimated using a radiative transfer model initialized by Earth-orbiting Cloud-Aerosol...

This document serves to substantiate the strong recommendations received from the scientific community that the acquisition of a mid-sized jet should be NCAR's highest priority...

The concentrations and sizes of smaller aerosols (radius smaller than 0.5 µm) in the marine atmosphere vary owing to natural and anthropogenic factors. The concentrations and...

High-resolution ocean biophysical models are now routinely being conducted at basin and global-scale, opening opportunities to deepen our understanding of the mechanistic...

Observed supercell updrafts consistently produce the fastest mid- to upper-tropospheric vertical velocities among all modes of convection. Two hypotheses for this feature are...

Cross-beam wind is usually estimated using a full correlation analysis (FCA) method applied to signals from spaced antennas. In this paper we present a cross-correlation ratio...
