Weather Balloons Provide Critical Data During Hurricane Season

During hurricane season, the National Weather Service relies on weather balloon launches to collect vital data for accurate forecasts. However, budget cuts and staffing shortages may limit these launches this year, potentially impacting predictive accuracy. Each balloon release is crucial for understanding storm direction and ensuring public safety.

Morehead City, N.C. — The National Weather Service is a key player in producing reliable weather forecasts, especially during the crucial hurricane season. In North Carolina, the Newport/Morehead City office is one of only two locations that conducts regular launches of weather balloons to gather vital meteorological data.

Ryan Ellis, a science and operations officer at the Morehead City weather service office, explained the process: “The idea is all balloons launch at the same exact time around the world. And then that data is fed into what we know as the forecast models.” He has been with the organization for six years and likened the launches to a coordinated dance of sorts.

Each day, the team releases a hydrogen-filled balloon, carrying a device known as a radiosonde that captures atmospheric data including humidity, wind speed, direction, atmospheric pressure, and temperature. “It’s also going to take the dew point,” Ellis noted, emphasizing that more frequent launches yield better accuracy in forecasts.

In North Carolina, Morehead City and Greensboro are the only two sites conducting these launches. Ellis pointed out that without balloons from regions like Roanoke, Virginia, and Charleston, South Carolina, gaps in data can occur. “If you miss one of those balloons, you have a really big gap in your data,” he said.

After about an hour and a half, the balloon reaches an altitude of 100,000 feet before it pops, with the weather service then using this data alongside airport observatory systems to create forecasts. In the event of severe weather, the frequency of launches is often increased to enhance predicting capabilities.

“The more data points you can get, the better off your model data is going to be,” Ellis explained. As weather conditions change unexpectedly, real-time data can be crucial for ensuring public safety.

Ellis also highlighted the importance of timely communication with emergency managers, especially for decisions like evacuating the Outer Banks. “The sooner we can get information to them, the more data and the more ability they have to make really high-stakes decisions,” he said. This continuous flow of information is vital during rapidly changing weather scenarios.

The data collected from the balloons is processed into computer models that help meteorologists understand steering currents for storms. However, as hurricane season for 2025 approaches, there’s some concern. Fewer balloon launches are being conducted nationwide due to federal budget cuts and staffing shortages.

Although the suspended sites are primarily outside North Carolina, the absence of data could still affect the local forecast. Weather patterns in the upper atmosphere further afield, such as in the western and central United States, can influence weather in the Carolinas just days later. This situation raises alarms about forecasting accuracy this season, as vital information on potential hurricane movement is at risk of being overlooked.

The reliability of weather forecasts, particularly during hurricane season, relies heavily on the data gathered from weather balloon launches. The National Weather Service’s launches in North Carolina are critical, but cuts to funding and staffing may hinder their ability to provide accurate predictions. As meteorologists continue to monitor and analyze weather patterns, the lack of data raises serious concerns for public safety and preparedness as storms approach this season.
