A balloon of unknown origin flying over sensitive areas in the US has been identified by China’s Foreign Ministry as a civilian airship used to collect meteorological data. The object was tracked by US defence officials but not shot down due to potential debris danger and limited intelligence gathering capabilities it could provide.

In a statement, China expressed regret for the balloon’s unintended entry into US airspace and said it had been blown off course by unexpected winds. The statement referred to the incident as an “unexpected situation” and said Beijing would continue to communicate with the US side.

The incident has raised questions about why weather balloons are still in use in an era of satellites and other advanced technology. Weather balloons are still an important part of meteorological data collection because they offer a relatively inexpensive way to measure atmospheric conditions in near-real-time, providing data that satellites simply cannot.

Weather balloons are also capable of providing measurements from far greater altitudes than ground-based instruments. This allows them to collect data on the upper atmosphere, including temperature, pressure, and wind speed. This data is then used to create models of the atmosphere which can help forecasters predict the weather more accurately.

Increasing China US tension

The Chinese balloon that entered US airspace likely got of course by accident, but it serves as a reminder that weather balloons are still in use and can be subject to unexpected winds and other unpredictable weather conditions. With tensions between the US and China already high, the incident is likely to increase mistrust between the two countries. This incident caused US Secretary of State Antony Blinken to postpone his visit to China next week.

The incident involving a Chinese civilian airship flying over sensitive areas in the US has highlighted the importance of weather balloons in collecting data about the atmosphere. Despite modern technology, weather balloons remain an essential tool for meteorologists due to their affordability and ability to measure conditions in near-real-time. The incident also serves as a reminder of how unpredictable atmospheric conditions can be and the danger of drifting balloons entering sensitive airspace.
