We can definitely say that cloud seeding enhances snowfall under the right conditions," said Sarah Tessendorf, a scientist at the National Center for Atmospheric Research (NCAR) and co-author of Quantifying snowfall from orographic cloud seeding, published in Proceedings of the National Academy of Sciences in late February.
WMO and the World Health Organization (WHO) have agreed on a roadmap to strengthen the provision and use of weather, climate, water and environmental information and services in evaluating human health risks and thereby improve health outcomes. The roadmap was developed by a group of experts from the health, weather and climate sectors representing research, operational, and policy interests.
The overall health and performance of WMO coordinated Global Observing System is under continued monitoring during the current COVID-19 outbreak. Large parts of the system, for instance its satellite components and many ground-based observing networks, are either partly or fully automated, and are therefore expected to continue functioning without significant degradation for several weeks, and in some cases even longer.
