COVID-19 severely affects weather and climate watch

The UN said that Meteorological measurements have declined amid the COVID-19 pandemic warning of this impact on weather forecasts and climate and atmospheric monitoring used to predict natural disasters.

In the report the UN’s World Meteorological Organization (WMO) cited the historic fires in Australia and the Amazon, record-shattering heat waves in Europe, and soaring levels of carbon dioxide in the atmosphere. In a statement released with the report, the leader of the United Nations calls climate change “the defining challenge of our time” and said “time is fast running out for us to avert the worst impacts of climate disruption.”

According to the World Meterological Organization Both the quantity and quality of weather observations and forecasts, as well as atmospheric and climate monitoring are at stake.

The WMO said that the Aircraft Meteorological Data Relay programme, which uses sensors on board commercial flights and other aircraft, usually produce more than 800,000 high-quality observations per day, including of air temperature and wind speed, along with temporal information.

However more than 260,000 people have been killed by the novel Coronavirus pandemic and it has a heavy toll on airline industry as the lockdown measures and travel restrictions have grounded flights worldwide.

As some of the regions have hit harder than others, with the southern hemisphere showing a loss of aircraft-based meteorological observations closer to 90 percent, said by United Nation agency.

Most of the global observation system uses satellites and ground-based networks, both partly or fully automated and therefore expected to continue functioning “without significant degradation for several weeks”.
