The power to Create forecasts and climate observations more difficult. “If there is less weather data from aircraft, and this is expected to decrease to say over a longer period of time, the reliability of weather forecasts,” said Lars Peter Riishojgaard, group Manager at the world meteorological organization (WMO) in Geneva.

Christoph Wittmann, head of the Department model development at the Central Institute for meteorology and geodynamics (ZAMG) in Vienna, agrees: “Due to the flight cancellations, an influence on the weather is definitely expecting models,” he said in an interview with the APA.

especially data, the aircraft flying at a height of between eleven and twelve thousand meters of supply, are now to a large extent. You are in addition to satellite images, the most important, even if only one of a number of other sources, especially for the creation of global models is significant.

Absence of this data, it is clear that the model quality suffers, grants Wittmann. What are the consequences this will have on the forecasts, exactly, is hard to estimate: “We are trying to compensate for this data deficiency with other observations.” So would now come more frequently than usual to the radio probes to be used.

Sensors on aircraft to provide the meteorologists, temperatures, and wind speeds and directions, information about the humidity, and turbulence. Because of the air traffic to mitigate the Corona pandemic is almost come to a Halt, has calculated the WMO for Europe in March, a dramatic collapse. Of more than 700’000, only a few Thousands of weather data per day were available. (SDA)
