Cub Scout and Webelos teaching area – to include tours of the GMU Geology labs – earn their Geology Cub Scout belt loop, or Webeloes Geology Pin and STEM award. ” Sunday is Scout Day” thou Scouts are welcomed both days – they are encouraged to come on Sunday when it is less crowded.
In Fall 2014, Dr. Kathy Pegion, who completed a PhD in Climate Dynamics with a dissertation on “Potential Predictability of Tropical Intraseasonal Variability…” in 2007, has joined the AOES faculty as an assistant professor of Climate Dynamics. Dr. Pegion rejoins the department after working as a research scientist at the Cooperative Institute for Research in Environmental Sciences (CIRES), a joint institute of NOAA and University of Colorado.
Dr. Pegion remembers that “One thing that I loved as a graduate student is the dynamic and collaborative environment amongst Climate Dynamics faculty” and hopes that “current students will benefit as much as I did from such a great environment.” She remarks that, “The biggest differences since I graduated are how much the program has grown and that the program is now located on campus, both of which I see as positive changes.”
Dr. Pegion’s research is aimed at aspects of the climate system that may be predictable on timescales of 2-weeks to a few years. This includes extending predictions of El Nino and La Nina to longer lead times using information from precursors. Other research of Dr. Pegion is aimed at understanding predictability at weeks 2-4 and improving predictions. This research includes work with the American Multi-model Ensemble project, a collaboration among several national laboratories and universities to improve climate prediction.
Dr. Pegion earned a BS in Meteorology and Computer Science, and an MS in Meteorology, from Florida State University. She is interested in how scientific results are utilized by experts in other fields. “The biggest challenges are that the kinds of climate information that are most relevant to people and decision makers are often the most difficult to predict (e.g. local, regional, extremes). How can we provide useful information even in low predictability situations?”
In an unprecedented collaboration involving research labs in several nations, AOES scientists are helping the Government of India accelerate progress in predicting the south Asian monsoon.
The monsoon is a seasonal shift of the climate that brings a tremendous amount of rain to India and surrounding countries in south Asia. That rainfall is essential to the livelihood, even survival, of hundreds of millions of people, and prediction of the Indian monsoon rainfall is critical for planning and risk mitigation across the sub-continent. Even a 10% departure from the anticipated normal rainfall can mean economic ruin or loss of life.
The Indian Ministry of Earth Sciences launched a major initiative in 2013, called the National Monsoon Mission, in which it enlisted the collaboration of research groups in Indian government labs, universities and labs and universities in the U.S. and other countries. The Center for Ocean-Land-Atmosphere Studies (COLA) in AOES is one of those U.S. labs making critical contributions to monsoon prediction capability. Under the overall direction of Prof. Jim Kinter, the project involves Profs. Paul Dirmeyer, Bohua Huang and Ed Schneider, each directing one aspect of the project, and three post-doctoral scientists: Drs. Rodrigo Bombardi, Subhadeep Halder and Chul-Su Shin, as well as several Ph.D. students in the Climate Dynamics program.
The three-year project is expected to radically improve the practice of monsoon prediction based on computer models of Earth's climate and directly impact the well-being of over a billion people.
