Climate Science without Climate Models

In June 2012, more than 3,000 daily maximum temperature records were broken or tied in the United States, according to the National Climatic Data Center (NCDC) of the US National Oceanic and Atmospheric Administration (NOAA). Meteorologists commented at that time that this number was very unusual. By comparison, in June 2013, only about 1,200 such records were broken or tied. Was that number “normal”? Continue reading

Extreme Events

Weather extremes capture the public’s attention and are often used as arguments in the debate about climate change. The concern that extreme events may be changing in frequency and intensity as a result of human influences on climate is real, but the notion of extreme events depends to a large degree on the system under consideration, including its vulnerability, resiliency, and capacity for adaptation and mitigation.

DIMACS/CCICADA Collaboration on REU and Other Sustainability Projects

The Center for Discrete Mathematics and Theoretical Computer Science (DIMACS) and the Command Control Interoperability Center for Advanced Data Analysis (CCICADA), both based at Rutgers University, have collaborated on some recent activities to enhance the summer experience for several undergraduate students participating in the DIMACS/CCICADA Research Experiences for Undergraduates (REU) program. DIMACS and CCICADA recently co-hosted a workshop on Science and Technology Innovations in Hurricane Sandy Research. Continue reading

Report on the Workshop “Stochastics in Geophysical Fluid Dynamics: Mathematical foundations and physical underpinnings”

Last week a workshop was held at the American Institute of Mathematics (AIM) in Palo Alto, California, around the theme of stochastic PDEs and applications in climate and weather modeling: “Stochastic in Geophysical Fluid Dynamics: Mathematical foundations and physical underpinnings.” The workshop brought together a lively mix of specialists in climate modeling and weather prediction alongside experts in the fields of deterministic and stochastic partial differential equations.
