The rank histogram filter (RHF) and the ensemble Kalman filter (EnKF) are assessed for soil moisture esti-mation using perfect model (identical twin) synthetic data assimilation...

We examine a deep precipitating system that formed over the west coast of India during 26–28 June 2002 producing heavy rainfall of 2-61 cm day−1. The system developed into a...

This paper synthesizes the efforts of an interdisciplinary, University-convened communication task force in the U.S. that used science communication theory to develop an...

The hydroxyl (OH), hydroperoxy (HO2), and organic peroxy (RO2) radicals play important roles in atmospheric chemistry. In the presence of nitrogen oxides (NOx), reactions...

Changes in “blue water”, which is the total supply of fresh water available for human extraction over land, are quite closely related to changes in runoff or...

We assess the magnitude of decadal to multidecadal (D2M) variability in Climate Model Intercomparison Project 5 (CMIP5) simulations that will be used to understand, and plan...

Two distinct snowfall events are observed over the region near the Great Lakes during 19-23 January 2007 under the intensive measurement campaign of the Canadian...

A coordinated set of large ensemble atmosphere-only simulations is used to investigate the impacts of observed Arctic sea ice-driven variability (SIDV) on the atmospheric...

Extreme winds and complex wave fields drive upper-ocean turbulence in tropical cyclone conditions. Motivated by Lagrangian float observations of bulk vertical velocity variance...

This paper presents the thermal forcing of the semidiurnal, terdiurnal, and 6-h components of the migrating tide induced by ozone heating in stratosphere and lower mesosphere....

Tropical cyclone (TC) forecast verification techniques have traditionally focused on track and intensity, as these are some of the most important characteristics of TCs and are...

Inner zone proton flux from 1980 to mid-2021 is examined using NOAA POES satellite data, indicating a long-term increase corresponding to a one hundred year minimum in solar...

Climate variability and weather phenomena can cause extremes and pose significant risk to society and ecosystems, making continued advances in our physical understanding of such...

We use the stratospheric/tropospheric chemical transport model MOZART-3 to study the distribution and transport of stratospheric O₃ during the remarkable stratospheric sudden...

A single column model with parameterized large-scale (LS) dynamics is used to better understand the response of steady-state tropical precipitation to relative sea surface...

We present a set of companion dynamical masses and orbital parameters of seven star systems from the NEID Earth Twin Survey with significant absolute astrometric accelerations...

The Southern Oscillation (SO) is usually described as the atmospheric component of the dynamically coupled El Niño - Southern Oscillation phenomenon. The contention in this...

This study presents the first research that assimilates the ground-based NEXRAD observations-derived two-dimensional (2D), azimuthally averaged radar radial velocity and...

The storm-time ionospheric-thermospheric (IT) state is of great interest, since the IT dynamics change dramatically as energy is input and dissipated in the upper atmosphere....

Record-breaking rainfall of 524.1mm in 24hr occurred in the coastal metropolitan city of Guangzhou, China, during 6-7 May 2017 and caused devastating flooding. Observation...
