To preserve forest health, the best management decision may be to do nothing

In newscasts after intense wind and ice storms, damaged trees stand out: snapped limbs, uprooted trunks, entire forests blown nearly flat.

In a storm’s wake, landowners, municipalities and state agencies are faced with important financial and environmental decisions.

A study by Harvard University researchers, supported by the National Science Foundation (NSF) and published in the journal Ecology, yields a surprising result: when it comes to the health of forests, native plants and wildlife, the best management decision may be to do nothing. (more…)

*Focus on deadly April 27, 2011, outbreak in Alabama and surrounding states*

It was one of the deadliest tornado outbreaks in U.S. history.

Now scientists are organizing a research program to better understand the tornadoes that blew through Alabama and other southeastern states on April 27, 2011.

Scientists at the University of Alabama in Huntsville (UAH) are analyzing radar data from that day, then merging the information with detailed storm surveys and other data. They hope to learn more about how the storms formed, what made the storms so powerful and what might be done to make tornado warnings more effective. (more…)

*Routine weather events can add up to huge annual economic impact*

Everything has its price, even the weather.

New research indicates that routine weather events such as rain and cooler-than-average days can add up to an annual economic impact of as much as $485 billon in the United States.

The study, led by scientists at the National Center for Atmospheric Research (NCAR), found that finance, manufacturing, agriculture and every other sector of the economy is sensitive to changes in the weather. The impacts can be felt in every state. (more…)
