Science

In this paper, scientists compare two approaches to next-generation E3SMhigh-resolution (HR) and multiscale modeling framework (MMF) configurations, to conventional low-resolution (LR) E3SM and observations (IMERG). 

Impact

Multiscale modeling framework E3SMv1 captures precipitation from mesoscale convective systems better than low- and high-resolution. High-resolution and multiscale modeling framework E3SM improves tropical cyclone precipitation. All configurations capture realistic extratropical cyclone precipitation in contrast to tropical cyclone and mesoscale convective systems, and conventional low-resolution E3SM does best.

Summary

Precipitation occurs in many different environments and is produced by a variety of weather phenomena in the United States, including tropical cyclones, extratropical cyclones, and mesoscale convective systems. This work quantifies the characteristics of precipitation in E3SM configurations associated with these storm types to better inform future development of the climate model and produce more accurate projections of future precipitation.
