Amid day-to-day weather forecasts and seasonal outlooks, there's a no-man's-zone of uncertainty one to two months out. A phenomenon called the Madden-Julian Oscillation may hold the key to better predictions in this intermediate period.
New research led by NCAR scientist Thomas Galarneau provides an in-depth analysis of two extreme weather events whose connection may come as a surprise: Russia’s intense heat wave in summer 2010 and the heavy rains that occurred simultaneously in Pakistan.
New research from NCAR is helping wind energy developers determine the best potential sites for capturing wind. Energy companies can lose money if they install turbines where winds are either too low to generate much power or so high that the turbines often need to be shut down to avoid damage.
NCAR scientists have performed one of the most detailed simulations ever of a massive tornado outbreak. They simulated two waves of tornadic storms that occurred on April 27,2011 in Alabama, the deadliest U.S. tornado day since 1925.
Every so often, a dome of upper-level high pressure sits in place for a few days, sometimes as long as several weeks. A major block can produce seemingly endless stretches of blazing heat or bitter cold. By the time it dissipates, it may leave behind a whole stack of broken weather records and an array of disastrous consequences.
The MetEd online training service covers topics in meteorology, weather forecasting, and related geosciences. Users can delve into everything from satellite meteorology to tsunami preparedness and forecasting dust storms.
Prior to massive flooding early in 2011, long-term drought plagued the Australian state of Queensland . As part of a broad research program on cloud seeding, NCAR researchers have been steadily crunching data from a 2008–09 field project that looked into how to make the clouds drop more rain on the region.
A new study led by NCAR’s Wei Yu and CU-Boulder’s Weiqing Han looks at the effects of the Madden-Julian Oscillation (MJO), the largest source of intraseasonal (within one season) variability in the tropics, causing wet and dry periods to alternate.
The surfeit of snowfalls across the U.S. East Coast over the last two winters brought ample evidence of just how much the white stuff can vary from place to place—and how difficult it is to assess accurately.
