NOAA’s Upcoming Weather Forecast Model Zeros In Earlier on Severe Weather

NOAA’s Upcoming Weather Forecast Model Zeros In Earlier on Severe Weather

Later this year, NOAA’s National Weather Service will usher into daily operations a sophisticated model called the High-Resolution Rapid Refresh, or HRRR, that will update forecasts hourly over the entire lower 48 United States at extremely sharp resolution using the latest observations from a network of ground and satellite-based sensors, radars and aircraft.

The HRRR provides forecast information at a resolution four times finer than what is currently used in hourly updated NOAA models.  This improvement in resolution from 13 to three kilometers is like giving forecasters an aerial photograph in which each pixel represents a neighborhood instead of a city.

NOAA launches research on next generation of high performance weather, climate models

NOAA launches research on next generation of high performance weather, climate models

NOAA and the U.S. Navy are teaming up with academic and other government scientists to design the next generation of powerful supercomputer models to predict weather, ocean conditions and regional climate change.

 

Four teams of scientists are beginning projects this month to rewrite computer models that will create faster, lower-cost, better integrated models.  These new models will take advantage of new supercomputers that use more energy efficient/lower-cost processors such as those originally developed for the video gaming industry.

New study: Rising temperatures challenge Salt Lake City’s water supply

New study: Rising temperatures challenge Salt Lake City’s water supply

In an example of the challenges water-strapped Western cities will face in a warming world, new research shows that every degree Fahrenheit of warming in the Salt Lake City region could mean a 1.8 to 6.5 percent drop in the annual flow of streams that provide water to the city.

NOAA Sea Grant awards $1.8 million to Sandy-hit states to better understand public response to coastal storm threats

NOAA Sea Grant awards $1.8 million to Sandy-hit states to better understand public response to coastal storm threats

NOAA Sea Grant this month announced $1.8 million in grant awards to Connecticut, New York, and New Jersey to enhance the American public’s ability to effectively plan, prepare and respond to natural disasters when they strike—particularly for major storms like Sandy, which resulted in 140 fatalities last year.

NOAA invests $1.3 million with university and federal researchers for hurricane forecasting advances

NOAA invests $1.3 million with university and federal researchers for hurricane forecasting advances

NOAA’s Office of Weather and Air Quality has funded seven multi-year proposals totaling $1.3 million this year for university partners and federal scientists to more rapidly and smoothly transfer new technology, research results, and observational advances through NOAA’s Joint Hurricane Testbed (JHT) to operational hurricane forecasting.

NOAA real-time beach and water quality data now available for Lake St. Clair

NOAA real-time beach and water quality data now available for Lake St. Clair

Independence Day is right around the corner, and Michigan's Lake St. Clair residents and tourists are gearing up for a holiday weekend filled with fishing, swimming and boating activities. Beach managers can now view NOAA water quality predictions in real-time, instead of waiting 24 hours as before, to make timely decisions to safeguard public health and avoid unnecessary beach closures.

New NOAA study in North Carolina may improve forecasting, lead times for dangerous storms

New NOAA study in North Carolina may improve forecasting, lead times for dangerous storms

This month, NOAA launched a 1½-year long pilot study in North Carolina to improve understanding and forecasting of dangerous storms that can lead to flooding and economic losses. From the coastline to the mountains, state-of-the-art NOAA instrumentation is being set up in numerous locations across the state that may improve forecasting and lead-time for tropical storms and summertime thunderstorms.

The origins of cirrus: Earth’s highest clouds have dusty core

The origins of cirrus: Earth’s highest clouds have dusty core

Scientists have found that wispy cirrus clouds have cores of dust and metallic particles, answering questions about how these clouds form and giving insight into their climatic implications in the future.

New study: Pace of climate zone shifts quickens as climate warms

New study: Pace of climate zone shifts quickens as climate warms

As our planet is warming, not only have Earth’s climate zones begun to shift – the pace of change is expected to accelerate, according to a new study led by the NOAA Cooperative Institute for Research in Environmental Sciences at the University of Colorado.

Scientists show climate patterns may influence extreme U.S. tornado seasons

Scientists show climate patterns may influence extreme U.S. tornado seasons

NOAA and university researchers believe they have found a climate signal related to a specific phase of the El Niño-Southern Oscillation that could be linked to, and possibly serve as a predictor of, massive tornado outbreaks.
