Zhang Records Storm Chasing Experience in Dramatic Video

Daile Zhang, Postdoctoral Associate at ESSIC/CISESS, recently posted a video on YouTube documenting a storm chasing trip she went on last May alongside Atmospheric Sciences graduate students and postdoctoral associates from the University of Arizona. On the trip, her group traveled through Texas, Oklahoma, Kansas, and Missouri looking for a tornado.  Unfortunately, they did not see a tornado. Instead, they saw some meso-scale storms that eventually turned into a tornado. Daile Zhang received …

Mishonov and Reagan Published on Gulf Stream Long-Term Variability

Two ESSIC/CISESS scientists, Associate Research Scientist Alexey Mishonov and Senior Faculty Specialist James Reagan, recently co-authored a paper in Scientific Reports titled, “Resilience of the Gulf Stream path on decadal and longer timescales”. The Gulf Stream is a part of the strongest oceanic pacemaker of the Atlantic Ocean and perhaps the entire Earth’s climate.  Understanding the long-term variability of the Gulf Stream path is critical for resolving how the ocean works as a …

New Study by Chen Could Help Predict Flash Droughts

ESSIC/CISESS Assistant Research Engineer L. Gwen Chen was lead author on a recent paper published in a special issue of Atmosphere titled “Flash Drought Characteristics Based on U.S. Drought Monitor”. The study discusses the characteristics of flash droughts, i.e. drought events with greater than or equal to two categories degradation in a four-week period based on the U.S. Drought Monitor.  In contrast with conventional droughts, which are mainly driven by precipitation deficits, flash …
