Abstract:
This study introduces the domestic marine meteorological drifting observer which can continuously, reliably and accurately observe the severe sea conditions based on Beidou navigation communication. It was independently developed by China and integrated with marine hydrological element (sea surface temperature, seawater salinity) and meteorological elements (air temperature, pressure, wind speed and direction). Up to now the observation test has been carried out in a number of sea areas. From 20 August to 5 September 2017, three drifting observers were placed in Guangdong Bohe Test Base for observing test, one on the shore, and the other two in the offshore seas. During the trial, the Typhoon Hato and the Typhoon Pakhar hit the area. The data analysis shows that the drifting observer data have a good correlation with the data from the national operation observation stations. The drifting observer obtained the observation data of air temperature, pressure and sea temperature in the period of typhoon weather, which had obvious characteristics of typhoon weather process, and showed a reasonable and apparent diurnal variation characteristic. The tests have shown that the marine meteorological drift observation instrument has the ability to perform actual observations under severe sea conditions.
