Met-ocean and Environment
From day-to-day weather forecasting to large-scale climate research, from land to sea, from surface hydrometeorology to space weather, Twilight's high-performance computers are active. Sugon's “send” super-calculation system for the National Meteorological Administration represents the super-calculation system. Beginning to lead China's own meteorological research work, while Sugon provides technology, products and solutions for the promotion of "smart weather".
Sugon 2nd-generation Computer Solution for Meteorology
1. Demand Analysis
These years, with the rapid development of urban construction and daily improvement of people’s livelihood, a higher requirement is posed for the meteorological departments to improve their service forecasting ability and their meteorological service level. Elaborate numerical forecasting is being carried out based locally across the country, which is a development trend advocated by China Meteorology Administration. However, mid-and-small meteorological departments of prefecture-level cities are faced with the following two challenges in carrying out the numerical forecasting service.
High-performance computer equipment usually needs to be installed in an expensive professional computer room. Many mid-and-small meteorological departments are not equipped with a professional computer room;
To carry out numerical forecasting requries specialists who are proficient in numerical modes and high-performance cluster environment and familiar with know-how on programing, operation and debugging, etc. under Linux system. But many departments are in lack of talents who are professional not only in meteorology, but also in high-performance computing.
2. Solution
Considering the problems such as high technical and equipment requirements existing in the current numerical meteorological forecasting, Sugon has designed an automatic mesoscale numerical forecasting product specially for mid-and-small meteorological bureaus of prefecture-level cities, namely, the 2nd-gneration computer for meteorology. The hardware computing platform is the personal high-performance computer (PHPC) customized by Sugon for the field of meteorology. In many areas, it has transcended the traditional rack-mounted server, blade server and cluster server, being a new generation of table-type high-performane computer featuring high stability, high performance and low environmental requirements. It adopts a design of integrative optimization, which can effectively cut the power consumption of the system. Plus the humanized design, strong system extensibility and excellent cost performance and computing density, it can meet the needs of office or even a severe environment. The software product adopts Sugon mesoscale meteorology forecasting system which is based on WRF. Each day the data of background field is downloaded, which can be imported with the data of ground-based upper-air sounding; it can automatically finish the pre-treatment, mode computing and post-treatment and generate WRF numerical product and graphic product. The computer for meteorology can be applied in mid-and-small meteorological departmetns of prefecture-level cities and used to solve the problems of mesoscale numerical weather forecasting with an accuracy of 3-15 km of prefecture-level cities.
