Abstract:
The European Center for Medium Range Weather Forecasts (ECMWF) has begun to offer high resolution products since January 2010, which affects the integrity of TIGGE data receiving in the China Meteorological Administration, causing significant data loss. The various factors affecting data receiving are analyzed, respectively. It is found that using the TCP transport protocol for data sharing has a bottleneck in application in the present network environment of high bandwidth and high time delay, which therefore restrains the network throughout and cannot satisfy huge data transmission requirements. The performance of TCP protocol and the throughput of current network are improved by adjusting the size of the TCP receiving window of the TIGGE system. Through adjusting, the situation of data receiving in the China Meteorological Administration is consistent with other global centers, realizing the integrity of data receiving of all global centers.
