A spatial model to examine rainfall extremes in Colorado's Front Range
Between 9th and 16th September 2013, northeast Colorado received some of its most extreme rainfall on record. The event affected 6 major rivers and their tributaries and 14...- publication PDF

Extension of the MURaM radiative MHD code for coronal simulations
We present a new version of the MURaM radiative magnetohydrodynamics (MHD) code that allows for simulations spanning from the upper convection zone into the solar corona. We...- publication PDF

Can the salt-advection feedback be detected in internal variability of the At...
Evidence for the assumptions of the salt-advection feedback in box models is sought by studying the Atlantic meridional overturning circulation (AMOC) internal variability in...- publication PDF

High resolution coupled climate-runoff simulations of seasonal snowfall over ...
Climate change is expected to accelerate the hydrologic cycle, increase the fraction of precipitation that is rain, and enhance snowpack melting. The enhanced hydrological cycle...- publication PDF

Machine learning the warm rain process
Clouds are critical for weather and climate prediction. The multiple scales of cloud processes make simulation difficult. Often models and measurements are used to develop...- publication PDF

Multi-century dynamics of the climate and carbon cycle under both high and ne...
Future climate projections from Earth system models (ESMs) typically focus on the timescale of this century. We use a set of five ESMs and one Earth system model of intermediate...- publication PDF

Theoretical expressions for the ascent rate of moist deep convective thermals
An approximate analytic expression is derived for the ratio lambda of the ascent rate of moist deep convective thermals and the maximum vertical velocity within them; lambda is...- publication PDF

Stratospheric ozone depletion: An unlikely driver of the regional trends in A...
It has been suggested that recent regional trends in Antarctic sea ice might have been caused by the formation of the ozone hole in the late twentieth century. Here we explore...- publication PDF

High-cadence visible and infrared spectra of the Sun during eclipse
We study novel spectra from 310 nm to 5.5 mu m obtained during the 2017 August 21 eclipse. Four spectrometers were deployed at Camp Wyoba (altitude 2402 m) on Casper Mountain,...- publication PDF
