ATOC welcomes Postdoctoral Research Associate Lei Zhang

Nov. 12, 2015

The Department of Atmospheric and Oceanic Sciences (ATOC) at CU Boulder is pleased to welcome new Postdoctoral Research Associate Lei Zhang. Dr. Lei Zhang joins the Oceans and Climate Lab from the Department of Atmospheric Sciences at the University of Hawaii. Previously, Lei earned bachelor's and master's degrees in Atmospheric Sciences from the Ocean University of China. Lei is a climate dynamicist interested in large-scale tropical ocean and atmospheric circulations, and will join a project focused on the impacts of changing climate on Pacific island-based defense installations funded by the Strategic Environmental Research and Development Program (SERDP) in collaboration with the Woods Hole Oceanographic Institution (WHOI).

Why scientists are so worried about the ice shelves of Antarctica

Oct. 13, 2015

When it comes to climate change, Antarctica is one of the world’s major places of concern, mostly because of the sheer amount of ice it contains — enough to theoretically cause about 200 feet of sea-level rise if it were all to melt — not that anyone thinks that will happen anytime soon. Still, smaller parts could be destabilized, and understanding how the Antarctic ice sheet will react to future climate change is a big priority for scientists.

Divergent trajectories of Antarctic surface melt under two twenty-first-century climate scenarios

Oct. 13, 2015

Ice shelves modulate Antarctic contributions to sea-level rise and thereby represent a critical, climate-sensitive interface between the Antarctic ice sheet and the global ocean. Following rapid atmospheric warming over the past decades, Antarctic Peninsula ice shelves have progressively retreated, at times catastrophically. This decay supports hypotheses of thermal limits of viability for ice shelves via surface melt forcing.

Two years out, lessons still being drawn from 'Great Colorado Flood'

Sept. 8, 2015

The storm that upended the lives of thousands of Front Range residents almost two years ago was nearly unprecedented for the area, so much so that it largely confounded the best efforts of those charged with forecasting its scope and impact.

ATOC welcomes Postdoctoral Research Associate Sloan Coats

Sept. 2, 2015

The Department of Atmospheric and Oceanic Sciences (ATOC) at CU Boulder is pleased to welcome new Postdoctoral Research Associate Sloan Coats. Dr. Coats joins Assistant Professor Kris Karnauskas' Oceans and Climate Lab from Columbia University's Department of Earth and Environmental Sciences (DEES) and Lamont-Doherty Earth Observatory (LDEO). Sloan is a climate dynamicist who employs paleoclimate evidence and climate modeling to better understand past changes to the means and extremes of climate.

Katja Friedrich: Investigating the Microphysics of Clouds and Precipitation

Aug. 20, 2015

Though precipitation and evaporation are ubiquitous phenomena across the globe, they are infamously difficult to measure and forecast. Dr. Katja Friedrich, Atmospheric and Oceanic Sciences (ATOC) Professor, is investigating the microphysics of clouds and precipitation, with specific attention to snowstorms, thunderstorms, and floods in mountainous and alpine regions. Her latest research focuses on measuring and forecasting evaporation from reservoirs in Colorado.

Kris Karnauskas: Melding Oceanography and Atmospheric Science to Study Climate

Aug. 20, 2015

By its nature, the study of climate is an interdisciplinary endeavor, necessitating the union of diverse and oftentimes disparate fields. Dr. Kris Karnauskas, new ATOC Assistant Professor and CIRES Fellow, is investigating climate dynamics and impacts, specifically in the tropics, by blurring the lines between oceanography and atmospheric science.

Julie Lundquist: Investigating the Science and Impacts of Wind Energy

Aug. 20, 2015

In an era of increasing concern for climate change, a growing emphasis has been placed on understanding the science, limitations and implications of renewable energy. Dr. Julie Lundquist, ATOC Assistant Professor and National Renewable Energy Laboratory (NREL) Research Scientist, is investigating the physical processes that govern wind energy, with an eye towards their societal impacts.

Shifting winds, ocean currents doubled endangered Galápagos penguin population

Aug. 6, 2015

Shifts in trade winds and ocean currents powered a resurgence of endangered Galápagos penguins over the past 30 years, according to a new study. These changes enlarged a cold pool of water the penguins rely on for food and breeding – an expansion that could continue as the climate changes over the coming decades, the study’s authors said.
