China has successfully developed a parallel computer system for a regional numerical weather forecast, which is expected to help improve the accuracy of China' s city and county level weather forecast.

The Shenjian-100 regional numerical weather forecast parallel computer system Tuesday passed the appraisal by experts organized by the Zhejiang Provincial Science and Technology Commission.

The system, developed in Huzhou of east China's Zhejiang Province, has an operational speed of 25.6 billion times per second.

It is learned that the price of the system is only one-sixth of the similar systems developed in other countries. Upgrading of the system is easy, experts said.

A 60-day trial operation of the system at the Huzhou Observatory shows that the accuracy rate of forecast for rainfall and clear weather within the time period of 24 hours, 36 hours and 48 hours is more than 90 percent.
