WACCM simulations: Decadal winter-to-spring climate impact on middle...
Energetic particle precipitation is one of the main processes by which the sun influences atmospheric composition and structure. The polar middle atmosphere is chemically...- publication PDF

Axisymmetric Tornado Simulations at High Reynolds Number
This study is the first in a series that investigates the effects of turbulence in the boundary layer of a tornado vortex. In this part, axisymmetric simulations with constant...- publication PDF

Electrification in mesoscale updrafts of deep stratiform and anvil clouds in Florida
Airborne observations in deep stratiform and anvil clouds showed extensive layers of 10- to 40-kV/m electric fields colocated with highly stratified uniform radar reflectivity...- publication PDF

Dynamical seasonal predictions of tropical cyclone activity: Roles of sea...
Climate models often show errors in simulating and predicting tropical cyclone (TC) activity, but the sources of these errors are not well understood. This study proposes an...- publication PDF

An implicit algebraic turbulence closure scheme for atmospheric boundary...
Turbulence parameterization plays a critical role in the simulation of many weather regimes. For challenging cases such as the stratocumulus-capped boundary layer (SCBL),...- publication PDF

High-resolution observations of the shock wave behavior for sunspot...
We present the first results of sunspot oscillations from observations by the Interface Region Imaging Spectrograph. The strongly nonlinear oscillation is identified in both the...- publication PDF

Nonstationary modeling for multivariate spatial processes
We derive a class of matrix valued covariance functions where the direct and cross-covariance functions are Matérn. The parameters of the Matérn class are allowed to vary with...- publication PDF
-
An agent-based modeling framework for examining the dynamics of the...
Hurricane evacuations involve many interacting physical-social factors and uncertainties that evolve with time as the storm approaches and arrives. Because of these complex and...- publication PDF

Generating probabilistic forecasts from convection-allowing ensembles Using...
"Neighborhood approaches'' have been used in two primary ways to postprocess and verify high-resolution ensemble output. While the two methods appear deceptively similar, they...- publication PDF

Tropospheric ozone changes, radiative forcing and attribution to emissions...
Ozone (Oâ) from 17 atmospheric chemistry models taking part in the Atmospheric Chemistry and Climate Model Intercomparison Project (ACCMIP) has been used to calculate...- publication PDF

Impact of the January 2012 solar proton event on polar mesospheric clouds
We use data from the Aeronomy of Ice in the Mesosphere mission and simulations using the Whole Atmosphere Community Climate Model to determine the impact of the 23-30 January...- publication PDF

Assessing the intensity of heatwaves in a warming climate at the urban...
Given that more than half of the world's population currently resides in cities, further understanding of the potential impact of future climate change on urban areas is needed....- publication PDF

Effect of the Atlantic hurricanes on the oceanic meridional overturning...
Hurricanes have traditionally been perceived as intense but relatively small scale phenomena, with little effect on the large scale climate system. However, recent evidence has...- publication PDF

Model predictability of hail precipitation with a moderate hailstorm case....
Explicit simulation of hailstorms remains a challenge partly due to the lack of accurate representations of both initial conditions and microphysical processes. Using a moderate...- publication PDF

Mesospheric temperature and circulation response to the Hunga...
The Hunga Tonga Hunga-Ha'apai (HTHH) volcanic eruption on 15 January 2022 injected water vapor and SO2 into the stratosphere. Several months after the eruption, significantly...- publication PDF

An overview of ARTMIP's tier 2 reanalysis intercomparison: Uncertainty in...
Atmospheric rivers, or long but narrow regions of enhanced water vapor transport, are an important component of the hydrologic cycle as they are responsible for much of the...- publication PDF

A scaling theory for the size distribution of emitted dust aerosols suggests...
Mineral dust aerosols impact Earth's radiation budget through interactions with clouds, ecosystems, and radiation, which constitutes a substantial uncertainty in understanding...- publication PDF
