[趣味英语]介绍一些常见天气的英文表达方法
Anticyclone/Area of high pressureWhen theatmospheric pressure over a region is higher than its surrounding, itis called an anticyclone or an area of high pressure. The air masssurrounding an anticyclone will move clockwise in the northernhemisphere. The weather under an area of high pressure is generallystable and fine.
Bright
The sky is covered by a large amount of thin cloud with sunshine occasionally.
Cloudy
The sky is covered with a total cloud amount of between six eighths and eight eighths.
Depression / Cyclone / Area of low pressure
Whenthe atmospheric pressure over a region is lower than its surrounding,the system is called a depression or cyclone. The area of a depressionhas no definite size and its diameter can range from 100 km to 2 000km. The weather under an area of low pressure is generally unstable.The air mass surrounding a depression will move counterclockwise in thenorthern hemisphere, and clockwise in the southern hemisphere.

Cold front
Theboundary line between an advancing cold air mass and a warm air mass.During the passage of a cold front, the local weather changes asfollows : pressure increasing, temperature falling, wind veering(clockwise change in direction), accompanied by showers andthunderstorms. Generally, the cold fronts in southern China is notstrong and may not bring so remarkable weather changes as mentionedabove.

Dew
Radiationcooling at night causes the air temperature to drop. When the airtemperature falls below the dew-point, which is the temperature thatthe air becomes saturated with moisture, some water vapour condensesfrom saturated air near the ground to form dew. Dew usually appears inthe early morning and condenses on grass or other ground objects.
Drizzle
Precipitation of water drops of very small size.
Fine
Thesky is covered by a total cloud amount of less than six eighths.However, it can still be described as fine even though the total cloudamount is greater than six eighths if the cloud layer is thin enough tolet plenty of sunshine to penetrate.
Fog, Foggy, Mist,
Misty, Haze, Hazy
Fogis the suspension of small particles formed by the condensation ofwater vapour in the air near the ground surface, reducing thevisibility to less than 1 000 m; it is called mist if the reducedvisibility is equal to or above 1 000 m; it is called haze if thevisibility is reduced due to small dust or smoke particles.
Rain
Precipitationof water drops from deep and thick cloud layers. It is more persistentthan showers but the rainfall amount is less.
Showers
Briefprecipitation usually from convective clouds. It is characterized bythe sudden start and end of the precipitation as well as the fineweather before and after its occurrence.
Sunny
Plenty of sunshine for most time of the day.
