El Niño One Possible Factor in 10 Year Major Hurricane Drought

According to a recent study released by the National Aeronautics and Space Administration (NASA), it has been ten years since a major hurricane has made landfall in the United States. Of course, this isn’t to suggest that the U.S. has been immune to hurricanes during this same timeframe; Infamous examples include Hurricane Sandy’s devastation to the Northeast U.S. in 2012 and the financial hardships brought about by Hurricane Ike in 2008. Yet neither of these storms met …

Loughner graphic-research featured by NASA Image of the Day

The air quality research of ESSIC / CICS-MD Scientist Chris Loughner was featured on May 26th as the “Image of the Day” on the NASA Earth Observatory website. The modeling study determined the number of high ozone days that would have occurred if NOx emissions had been 2002 levels during July 2011. The results estimated a reduction of three to nine Red/Orange Code days, as shown in the figure below. The post also quoted Loughner: The benefit of regional emissions reductions …

New Models Allow for Better Drought Monitoring in Southern Africa

A recent drought in southern Africa has led to massive declines in crop production and food availability throughout the region. According to the World Food Program, the United Nations’ food aid division, the shortages are predicted to put millions at risk of starvation in an area already plagued by poverty and malnutrition. The shortage of rainfall was attributed to the 2015-16 El Nino Southern Oscillation (ENSO), which led to unusually high temperatures and a 50% crop reduction in …
