Antarctic extreme snowfall: A CloudSat and CALIPSO satellite perspective
(2024)The Antarctic Ice Sheet is a critical component of the Earth’s climate system, with its role in global sea level regulation becoming increasingly significant in a warming climate. Snowfall is a key factor in ice mass ... -
Saharan dust impact on radiative heating rate errors inherent in reanalysis data in the African Easterly Wave development region
(University of Wisconsin-Madison, 2024)Saharan dust outbreaks strongly impact the atmosphere’s energy balance, as their radiative effects can alter atmospheric heating rates by several degrees per day. However, numerical weather prediction models often struggle ... -
Environmental Conditions Impacting Late-Summer Sea Ice Concentration Predictability in the Northwest Passage
(University of Wisconsin-Madison, 2024)The Northwest Passage, located in the Canadian Archipelago, is a conglomerate of sea routes that connect the eastern and western sides of the North American continent. Historically, sea ice in the region has made it difficult ... -
Impact of tropical and boreal biomass burning on atmospheric composition
(University of Wisconsin-Madison, 2024)Atmospheric trace gases and aerosols emitted from biomass burning significantly influence atmospheric composition globally and locally on short-term and climatological time scales. Global chemical transport models (CTMs) ... -
Modeling and assessing the impact of nocturnal NOx chemistry on air quality
(2024)Nitrogen oxides (NOx ≡ NO + NO2) are air pollutants in the United States because they have direct human health impacts and play a central role in the production of secondary pollutants like ozone and particle pollution. ... -
Environmental controls of vertical motion over the maritime tropics
(University of Wisconsin-Madison, 2023)Understanding what controls vertical motion profile shape is fundamental to understanding tropical precipitation patterns. There is not a comprehensive understanding of what controls the top-heaviness of vertical motion ... -
Development and application of adjoint sensitivity to potential vorticity and unbalanced flows in a numerical weather prediction model
(University of Wisconsin-Madison, 2023)The adjoint of a numerical model provides a tool to measure the sensitivity of a chosen forecast aspect to small model state perturbations in the earlier time. For the response function describing the growth or behavior ... -
A phase plane based perspective of energetics of large scale tropical convection
(University of Wisconsin-Madison, 2023)Rainfall and convection in the tropics has huge impacts on the lives and livelihood of almost 40 percent of the global population that resides there. However, we still lack a complete understanding of the full spectrum of ... -
Characterizing deep convective cloud properties and their energetic impacts in satellite observations
(University of Wisconsin-Madison, 2023)Because atmospheric deep convection plays an important role in influencing Earth’s global energy budget, it is increasingly important to consider how deep convective cloud and energetic properties might change due to a ... -
Land-atmosphere interactions over the Indonesian Maritime Continent
(University of Wisconsin-Madison, 2023)The “Maritime Continent” (MC) is the largest archipelago in the tropical region, consisting of over 22,000 islands and inhabited by more than 400 million people. This region has a significant impact on global atmospheric ... -
A macrosystems approach towards improved understanding of interactions between forest management, structure, function and climate change, and implications for the terrestrial carbon cycle
(University of Wisconsin-Madison, 2023)Forests constitute a significant global carbon sink that continues to expand in size, in addition to supporting a range of environmental, economic, and social co-benefits. Forests interact with the overlying atmosphere ... -

(University of Wisconsin-Madison, 2024) -
Trends in the waviness of the Southern Hemisphere subtropical and polar jets
(University of Wisconsin-Madison, 2024-05-07) -
Investigating the diurnal cycle in 9 km ECMWF potential vorticity variability in the upper troposphere and lower stratosphere over Gulf Coast tropical cyclones
(University of Wisconsin-Madison, 2024-04-30) -
Characterization of far-infrared polar spectral signatures for PREFIRE
(University of Wisconsin-Madison, 2023) -
The influence of climate change on Arctic atmospheric rivers and the impacts on sea ice
(University of Wisconsin-Madison, 2023) -
Examining the links between the Quasi-Biennial Oscillation, the Madden-Julian Oscillation, and the El Niño-Southern Oscillation using linear inverse modeling
(University of Wisconsin-Madison, 2023) -
Near-storm environmental relationships with tropical oceanic convective structure observed during NASA CPEX and CPEX-AW
(University of Wisconsin-Madison, 2023) -
Automated objective identification of occluded sectors in midlatitude cyclones: method and some climatological applications
