Earlier this Winter Spain and woldwide media in talked about Dr Judah Cohen’s weather predictions. Dr. Cohen is a Massachusetts scientist who had spent several years making North America and Europe winter seasonal predictions with a really high success rate, even up to 75 %. A percentage that clearly exceeds those others from the main and most prominent meteorological centers worldwide.
In Meteovigo we had the pleasure to meet and interview Dr Cohen and now we want to share and disseminate this interview, where a friendly D. Cohen admits that he loves Spain, has already visited us and wish to return on holidays.
We must admit that we were pleasingly surprised to see the love and dedication that Dr.Cohen brigns to his work and above all the humility with he continues working even though right now his company has the highest success rate with significant difference in mid-latitude long term forecasting.
Dr. Cohen joined Atmospheric and Environmental Research in 1998. Prior to AER, he spent two years as a National Research Council Fellow at the NASA Goddard Institute for Space Studies after two years as a research scientist at MIT’s Parsons Laboratory. Cohen received his Ph.D. in Atmospheric Sciences from Columbia University in 1994 and has since focused on conducting numerical experiments with global climate models and advanced statistical techniques to better understand climate variability and to improve climate prediction. Cohen develops AER’s long range forecast products for commercial clients who include some of the largest investment firms in the US. He’s been interviewed on television, the Wall Street Journal, Boston Globe, and Investor’s Business Daily, among others. His work is highlighted by the National Science Foundation (NSF).
Dr. Cohen has a Research Affiliate appointment in the Civil Engineering Department at Massachusetts Institute of Technology (MIT) and is a member of the American Meteorological Society (AMS) and the American Geophysical Union (AGU). He has published over two dozen articles on seasonal forecasting in their journals and others. Most recently, Dr. Cohen was appointed Associate Editor of the Journal of Climate, a peer-reviewed publication of the AMS.

In high school for science class I did a report about severe weather. I really enjoyed researching and writing the report and I also recieved an A+ as my grade. After that report, I knew that I wanted to study meteorology as long as possible.
The model did produce a very interesting response in the weather but the response was not isolated to North America but was hemispheric in scale and the pattern of variability most closely resembled the North Atlantic or Arctic Oscillation. This pattern also strongly projects onto the strength of the polar vortex, a term that has been used widely in the media here in the United States the past two years.
I then found a similar relationship in the observations. After further modeling experiments and more observational analysis we found that Eurasian snow cover had a bigger impact on winter weather than North American snow cover and that the month when snow cover had the biggest impact on winter weather was October. During October most of the snowfall that takes place in Eurasia, is over Siberia.
(Cohen sent us this selfie that this winter was one of the heavy snowfall.)
