This study primarily examines the variability of zonal winds in the geomagnetic “quiet‐time” (AE index < 190 nT; Kp index < 2)...

The vertical structures of a leading outflow boundary ahead of a continental nocturnal MCS and of the upstream environment are examined in order to answer the question of...

The three-parameter gamma distribution n( D) 5 N0Dmu exp(-LambdaD) is often used to characterize a raindrop size distribution ( DSD). The parameters m and L correspond to the...

A new data source from ground-based stations that track global navigation satellite system (GNSS) transmitters has been implemented in the Navy Global Environmental Model...

Organic compounds can enhance the hygroscopic properties of insoluble dust particles and thereby affect their cloud condensation nuclei activity in the atmosphere. In this...

Photospheric faculae are markers of the solar magnetic field, appearing as bright regions along the edges of granules on the Sun's surface. Using data from the Debrecen Solar...

The daily amplitude of the solar quiet (Sq) magnetic variation of the horizontal intensity, H, of observatories at low and midlatitudes is analyzed, in search of significant...

The nondipolar portions of the Earth's main magnetic field constitute substantial differences between the two hemispheres. Beside the magnetic flux densities and patterns being...

A small, isolated, short-lived cumulus congestus was studied using primarily a10 cm radar, a cloud penetration with an instrumented sailplane, and time-lapse photography froman...

The theoretical accuracy of baseline winds, estimated using spaced antennas (SA) and a full correlation analysis (FCA) method to process signals in the presence of noise, is...

A National Science Foundation sponsored educational deployment of a Doppler on Wheels radar called the Hawaiian Educational Radar Opportunity (HERO) was conducted on O'ahu from...

We compare the precipitable water vapor (PWV) determined using a domestic ground-based microwave radiometer (MWR PWV) with PWV measurements from radiosondes (RS PWV), the Global...

Key differences between urban and rural populations can influence the adoption and impacts of new cooking technologies and fuels. We examine these differences among urban and...

The relationship between atmospheric boundary layer (ABL) depth uncertainty and uncertainty in atmospheric transport and dispersion (ATD) simulations is investigated by...

Superrefraction at the top of the atmospheric boundary layer introduces problems for assimilation of radio occultation data in weather models. A method of detection of...

This study investigates the impact of initial conditions/boundary conditions (ICs/BCs) and horizontal resolutions on forecast for average weather conditions, focusing on low-...

Fossil fuel combustion has increased atmospheric CO₂ by ~ 115 µmol mol-1 since 1750 and decreased its carbon isotope composition (δ¹³C) by 1.7-2‰ (the ¹³C Suess...

A coupled chemistry climate model, the Whole Atmosphere Community Climate Model was used to perform a transient climate simulation to quantify the impact of geoengineered...

Aerosol particles play a critical role in the tropical tropopause layer (TTL) through cloud formation and heterogeneous chemistry, influencing the radiative and chemical balance...
