9-day Weather Forecast

Full Version / Simplified Version

General Situation:

Under the dominance of the subtropical ridge, it will remain generally fine and very hot over southern China in the next couple of days. An area of low pressure over the central part of the South China Sea is bringing unsettled weather to the region, and will develop progressively and move in the general direction of Hainan Island in the next few days. With the gradual weakening of the subtropical ridge in the middle and latter parts of next week, it will be more showery over the south China coast.

Note:
  1. This middle 50% range (between 25th and 75th percentiles) is calculated based on the maximum/minimum temperature and relative humidity data within a 5-day period centred on that day in the 30 years from 1981 to 2010.
  2. "9-day Weather Forecast" provides general indications of the trends in weather for the coming 9 days. For detailed description of today's weather forecast, please refer to "Local Weather Forecast".
  3. The accuracy of forecast generally decreases with forecast period. The average accuracy of weather forecast for the next one to three days, four to seven days, and eight to nine days are about 90%, 85% and 80% respectively.
  4. The accuracy of forecast also varies for different weather systems in different seasons. Generally speaking, weather in spring and summer such as fog, tropical cyclone and severe convective weather is more changeable, resulting in higher uncertainty of forecast.
