New York Times article: Forecasters Face Loss of Data as Weather Balloon Flights Are Cut, https://nyti.ms/3uVqeIv, published 5 April 2022.
The National Weather Service has cut back on weather balloon launches at some of its sites because of shortages of hydrogen and helium used to lift them, potentially affecting forecasts and weather and climate research.
The cutbacks, coupled with the closing of a launch site on Cape Cod last year that has yet to reopen, could especially affect forecasting in the New York-New England area, some scientists said.
“We can’t go back and get that data,” said Sandra Yuter, a professor at North Carolina State University and an expert on remote sensing of meteorological data. “We’re going to have big gaps.”
Dr. Yuter said the cutbacks showed that the weather service was not placing high enough priority on weather balloons, which have been a staple of the agency’s observations for nearly a century.
Dr. Yuter said that balloon data helps scientists understand the structure of the atmosphere and “feeds into our understanding of what will happen as the climate changes.”
During January 2022, group members Matthew Miller, Kevin Burris, Luke Allen, Laura Tomkins, and Sandra Yuter all had key roles in the NASA Investigation of Microphysics and Precipitation for Atlantic Coast-Threatening Snowstorms (IMPACTS) field program.
An article about the research flight on 29 Jan 2022 during an east coast blizzard was published in Popular Science.
Our research utilizing a relational database of matched weather forecasts and observations has been published in the AGU journal Geophysics Research Letters. (link to article)
We evaluated the output from weather forecast models compared to observations at 210 airports across the United States during the November 2019 to March 2020 winter season. We focused on near-surface air temperature errors in the Global Forecast System (GFS) and High- Resolution Rapid Refresh (HRRR) weather models for different times of day and subsets of observed weather conditions. The GFS is 1°C too warm at night and 2°C too cold during the day in conditions with <= 50% and <= 25% cloud cover. The daily high and low temperatures have smaller errors in the HRRR model, which has different algorithms than the GFS model. Model refinement and development efforts would benefit from a focus on accurate representation of the diurnal cycle of temperatures as this basic characteristic of weather can reveal strengths and weaknesses in the model physics.
