Researchers Develop Method to Better Predict Severity of Tornado Outbreaks

Weather forecasters would love to be able to predict the severity of tornado outbreaks, giving those in their path potentially life-saving information. Now, using new experimental high-resolution forecast models, researchers have developed a method to help forecasters better predict the severity of tornado outbreaks. A report on this work by scientists at NOAA’s National Severe Storms Laboratory and the NOAA Cooperative Institute for Mesoscale Meteorological Studies at the University of Oklahoma is available online and will be included in the April 2013 print edition of the journal of Weather and Forecasting.

Satellite Imagery Helps Fight Locust Plagues in North Africa

DMC International Imaging (DMCii) is helping The Algerian Space Agency (ASAL) to predict the spread of locust plagues across North Africa as part of a pro-active approach to tackle the destructive phenomenon using satellite imagery. Every year, North Africa is subjected to locust plagues that threaten to decimate crops and endanger countries’ food security. The satellite imagery is used to assess vegetation conditions, which helps to predict the locations of locust breeding grounds. The imagery, from the UK-DMC2 satellite, is used in conjunction with weather data to help create locust forecasts and focus the application of pesticides to prevent the spread of swarms.

Land Loss in Coastal Louisiana Since 1932

Every year, 25-35 square miles of land off the coast of Louisiana—an area larger than Manhattan–disappears into the water due to a combination of subsidence (soil settling) and global sea level rise. The maps above show how much land has been lost to the Gulf of Mexico in the past 80 years.
