Observations of hurricane position, which in practice might be available from satellite or radar imagery, can be easily assimilated with an ensemble Kalman filter (EnKF) given...

A three-dimensional numerical meteorological model is used to perform large-eddy simulations of the upslope flow circulation over a periodic ridge-valley terrain. The subgrid-...

Mathematical models have been used to understand the transmission dynamics of infectious diseases and to assess the impact of intervention strategies. Traditional mathematical...

The National Center for Atmospheric Research Community Atmosphere Model (version 3.5) coupled with the Morrison–Gettelman two-moment cloud microphysics scheme is employed to...

Slant wet delay (SWD) measurements from a ground-based GPS observation network provide accurate, high-resolution moisture information for mesoscale analysis. In this study, we...

Highly accurate and stable observations -- beyond those provided by routine weather monitoring -- are essential for understanding the behavior of the climate system, developing...

Net primary production (NPP) by plants represents the largest annual flux of carbon dioxide (CO₂) from the atmosphere to the terrestrial biosphere, playing a critical role in...

This study focuses on the effects of polar mesospheric cloud (PMC) formation on the chemical environment of the mesosphere and lower thermosphere. Of specific interest is how...

Magnetic field emerges at the surface of the Sun as sunspots and active regions. This process generates a poloidal magnetic field from a rising toroidal flux tube; it is a...

This paper uses a case study to explore the potential of Constellation Observing System for Meteorology. Ionosphere, and Climate (COSMIC) and Challenging Minisatellite Payload...

This article does not have an abstract or article summary.

Rapid adjustments are responses to forcing agents that cause a perturbation to the top of atmosphere energy budget but are uncoupled to changes in surface warming. Different...

Microphysics parameterizations in large-scale models often account for subgrid variability in the calculation of process rates by integrating over assumed subgrid distributions...

In this study, the dynamical processes contributing to warm-core meso-β-scale vortex formation associated with the 8 May 2009 "super derecho" are examined utilizing two...

The effects of tuning of length-scale and observation-error on heavy rainfall forecasts are investigated. Length scale and observation error are tuned based on observation minus...

Demanding the compatibility of semi-Lagrangian trajectory schemes with the fundamental Euler expansion formula leads to the Monge-Ampère (MA) nonlinear second-order partial...

Geoengineering with stratospheric sulfate aerosols can, to some extent, be designed to achieve different climate objectives. Here we use the state-of-the-art Community Earth...

While the fundamental understanding of tropical cyclone (TC) movement is fairly mature, notable advancements are still being made. This paper summarizes new concepts and updates...

Unsteadiness and horizontal heterogeneities frequently characterize atmospheric motions, especially within convective storms, which are frequently studied using large-eddy...

Ambient surface level concentrations of isoprene (C(5)H(8)) were measured in the major forest regions located south of Shanghai, China. Because there is a large coverage of...
