Tomorrow there will be a big snowfall.

The train was delayed because of heavy snowfall.

Eastern and southern Tajikistan also experienced heavy snowfall, with nearly 2 million people affected in the Rasht valley.

Heavy snowfall closed several key link roads, hampering the delivery of badly needed foodstuffs to populations in the south.

In August 2004, the drought in Afghanistan entered its sixth year as rain and snowfall remained significantly below average.

Heavy rains in the Khatlon region further damaged the infrastructure that had already been adversely affected by high levels of snowfall.

Affected by a stronger cold front, temperatures in many parts of Shandong Province have fallen sharply, and snowfall occurred on Mount Tai in the morning.

Early in 2005 most of the Central Asian region suffered from adverse weather conditions heavy rains and snowfall were reported throughout Afghanistan, Pakistan and Tajikistan.

Because Mongolia was vulnerable to snowfall, drought, flash floods and earthquakes, it had adopted a new law to strengthen its disaster management system and created the National Disaster Management Agency.

This change in the amount and pattern of rainfall has serious implications for many economic activities, as well as for countries preparedness to handle emergencies such as large scale coastal flooding or heavy snowfall.

If the Arctic Ocean becomes ice free in summer, the melting and the snowfall will probably increase sharply. At that point, the precautionary principle might suggest that we take drastic action to stop burning fossil fuels.

The air surrounding Greenland and Antarctica has recently become warmer and more humid. Warm and humid air will increase melting of ice in low regions at the edges of the ice sheets while boosting snowfall over cold high regions in the interior.

It would be unfortunate if China and India were to impoverish themselves by ceasing to burn coal, only to have the resulting decrease of snowfall over Greenland and Antarctica cause sea levels to rise faster. The precautionary principle is not a useful substitute for scientific understanding.
