Step 1: Warming up by looking and saying
Please look at the photo on the screen. What is it? Yes, it is sandstorms.
Cold snap brings sandstorms
The warm spring in North China is sometimes interrupted with cold air and spread of sandstorms.
According to weather experts, many areas of Shaanxi, Shanxi, and Hebei provinces and western regions of Northeast China experience dust storms in spring.
Although different areas see dust affected weather of varying degrees, a sharp drop in temperature is experienced across the entire region.
Increasing desertification is the main reason for the frequent sandstorms in North China in recent years.
However, compared with the years from 1999 to 2002, 2006 has so far seen far fewer sand storms.
One reason 2006 has seen fewer sandstorms is that there was a lot of rain and snow in Northern China last winter, providing favorable conditions for spring vegetation.
Warming up by learning about BACKGROUND INFORMATION
Sandstorms, i.e., strong winds filled with dust particles, blow through North China frequently. Northern China's Inner Mongolia Autonomous Region and Hebei Province have been primary sources of sandstorms in previous years. Meteorologists said this type of weather is caused by frequent movements of cold air over the regions and increased dryness due to rising temperatures in Spring, making surface soil easily blown away.
