Bimodality in simulated precipitation frequency distributions and its relationship with convective parameterizations

Npj Climate and Atmospheric Science
Bimodality in precipitation frequency distributions is often evident in atmospheric models, but rarely in observations. This study i) proposes a metric to objectively quantify the bimodality in precipitation distributions, ii) evaluates model simulations

Realistic Precipitation Diurnal Cycle in Global Convection‐Permitting Models by Resolving Mesoscale Convective Systems

Geophysical Research Letters
Accurately representing the precipitation diurnal cycle has long been a challenge for global climate models (GCMs). Here we evaluate the precipitation diurnal cycle in the DYAMOND global convection‐permitting models (CPMs) and CMIP6 HighResMIP models ...

What Sets the Tropical Cold Point in GSRMs During Boreal Winter? Overshooting Convection Versus Cirrus Lofting

Earth and Space Science
The cold point tropopause, the minimum temperature within the tropical upper troposphere‐lower stratosphere region (UTLS), significantly impacts Earth's climate by influencing the amount of water vapor entering the lower stratosphere. Understanding which

Intercomparison of Cloud Properties in DYAMOND Simulations over the Atlantic Ocean

Journal of the Meteorological Society of Japan. Ser. II, 2021
We intercompared the cloud properties of the DYnamics of the Atmospheric general circulation Modeled On Non-hydrostatic Domains (DYAMOND) simulation output over the Atlantic Ocean. The domain averaged outgoing longwave radiation (OLR) is relatively similar across the models, but the net shortwave radiation at the top of the atmosphere (NSR) shows large

Tropical Free‐Tropospheric Humidity Differences and Their Effect on the Clear‐Sky Radiation Budget in Global Storm‐Resolving Models

Journal of Advances in Modeling Earth Systems, 2021
Reducing the model spread in free‐tropospheric relative humidity (RH) and its response to warming is a crucial step toward reducing the uncertainty in clear‐sky climate sensitivity, a step that is hoped to be taken with recently developed global storm ...

Convection‐Permitting Simulations With the E3SM Global Atmosphere Model

Journal of Advances in Modeling Earth Systems, 2021
This paper describes the first implementation of the Δx = 3.25 km version of the Energy Exascale Earth System Model (E3SM) global atmosphere model and its behavior in a 40‐day prescribed‐sea‐surface‐temperature simulation (January 20 through February 28,
