China’s Implementation of Impact and Risk-based Early Warning
China is one of the countries most affected by meteorological hazards. From 1984 to 2014, on average per annum meteorological hazards caused 4 066 deaths and 192.2 billion Chinese Yuan Renminbi (CNY, US$ 30.5 billion) direct economic losses – 2% of the Chinese Gross Domestic Product (GDP). The annual average loss ratio (direct economic losses/annual GDP) halved from 2.08% from 1984 to 2000 to 1.03% from 2001 to 2014, thanks to improved disaster prevention and mitigation measures. That 1.03% ratio is still 8 times higher than the global average (0.14%) and 3 times higher than that of the United ...

The Weather: What’s the Outlook?
New sources of atmospheric observations, faster supercomputers and advances in science together revolutionized weather forecasting in the latter part of the 20th century. On the global scale, we can today predict up to five days ahead as accurately as we could do for three days 20 years ago. This means society has much more advance warning of weather hazards than before, permitting people to prepare and, thereby, limit the loss of lives and property. Expectations are high for even greater advances in the years to come.

Forecasting Heavy Rains and Landslides in Eastern Africa
Good rainfall draws many people to settle across the eastern Africa highlands for farming and other businesses. However, factors such as steep terrain, logging, livestock grazing, agriculture, and construction, have increased erosion and contributed to less stable slopes. These factors can lead to devastating landslides and mudslides, especially during episodes of very heavy rain. Forecasting and monitoring heavy rainfall is challenging, especially in mountainous regions that have few surface observations. This make satellite data critical for meteorologists and hydrologists forecasting for th ...
