VOInews, Geneva : The World Meteorological Organization (WMO) has issued its annual report on the incidence of sand and dust storms, as well as their impacts on society. Dust concentrations in the worst hit areas in 2023 were above the long-term average, but slightly lower than 2022, it says.

The most severe storm of the year swept across Mongolia in March 2023, affecting more than 4 million square kilometres, including 20 provinces in China, according to the Airborne Dust Bulletin.

It was released for the International Day of Combating Sand and Dust Storms on 12 July.

Every year, around 2,000 million tons of dust enters the atmosphere, darkening skies and harming air quality in regions that can be thousands of kilometers away, and affecting economies, ecosystems, weather and climate. Much of this is a natural process, but a large part of it is the result of poor water and land management.

“We need to be vigilant in the face of continuing environmental degradation and current and future climate change. Scientific evidence shows that human activities are having an impact on sand and dust storms. For example higher temperatures, drought and higher evaporation lead to lower soil moisture. Combined with poor land management, this is conducive to more sand and dust storms,” said WMO Secretary-General Celeste Saulo.

According to a release received by Voice of Indonesia on Friday (12/07/24), monitoring and forecasting accuracy has improved in recent years due to the progress of numerical models and observation systems. The WMO Sand and Dust Storm Warning Advisory and Assessment System (SDS-WAS), set up in 2007, strives to improve warnings through dedicated regional centres and combines research and operational work.

The global average of annual mean surface dust concentrations in 2023 was slightly lower than that in 2022, mainly due to reduced dust emissions from several dust-active regions around the world, such as North Africa, the Arabian Peninsula, the Iranian Plateau, northern India, central Australia and north-western China//VOI
