Progress in the research of the hottest semi subme

Progress has been made in the research of semi submersible ocean weather detection unmanned craft

China has a long coastline, developed coastal economy, and vast waters near continents and islands, which contain rich resources. With the implementation of the maritime power and the "the Belt and Road" strategy, maritime transportation, fishery breeding, oil and gas exploitation, scientific research, tourism and military activities are increasingly frequent. However, the climate in China's coastal areas and adjacent sea areas is changeable, and the meteorological conditions and sea and land environment are complex. Marine meteorological disasters such as typhoon, rainstorm, gale, storm surge, fog and strong convective weather at sea often occur. At present, there are still many deficiencies in the scientific understanding of the evolution of these marine disastrous weather, which makes it difficult to accurately predict these marine disastrous weather, and the lack of meteorological observation data at sea, especially in the open sea, is the main reason

meteorological observation data on the sea are mainly provided by satellite remote sensing, merchant marine weather reports and non operational aircraft observations in developed countries and regions, but compared with the data provided by land and earth stations, there is a great gap in quality and quantity, which cannot meet the needs of scientific research and business. This situation limits the in-depth study of typhoon generation and development mechanism, air sea interaction and climate change related to El Nino events, and greatly hinders the improvement of Marine Meteorology and hydrological environment prediction, especially typhoon weather prediction ability. There are very few meteorological and hydrological observation stations in the vast waters around China, and there are not many buoys arranged near the sea. Merchant ships can only provide discontinuous and scattered meteorological and sea state reports, while marine surveillance aircraft cannot provide meteorological and hydrological information in bad weather; The meteorological sounding of islands and comprehensive investigation ships is few, and the troposphere profile detection with wide coverage and continuous time is lacking

at present, China still lacks effective and economic technical means in offshore meteorological observation, especially in marine vertical sounding observation, due to the rise and fall of the spot market of steel raw materials on June 7. At home and abroad, there is no long-term unmanned sounding marine meteorological observation system, especially there is no marine automatic navigation special platform and integrated observation technology that can survive in complex sea conditions and suitable for meteorological detection. In order to change this situation as soon as possible, it is necessary to develop the in-situ detection technology of marine meteorological environment, which is automatically deployed at sea and can survive under any sea condition, and develop a new marine meteorological and hydrological observation platform shared by scientific research and business

in May 2016, the unmanned vehicle research and development team of the Institute of Atmospheric Physics of the Chinese Academy of Sciences successfully developed a semi submersible dedicated unmanned vehicle for ocean meteorological observation based on self-control driving. The boat is a semi submersible structure, most of the boat body is below the waterline, and only the equipment warehouse is above the water surface, which greatly reduces the impact of waves on the boat body and makes the navigation of the unmanned boat very stable; At the same time, the center of gravity of the unmanned craft is far lower than its floating center, which makes the unmanned craft have the function of self righting, and greatly improves its survival ability in bad sea conditions

from May 2016 to November 2017, the semi submersible ocean meteorological observation unmanned vessel carried out a series of river and sea trials in the Huaihe River and Bohai Sea, tested the function, technical maturity and operational feasibility of the semi submersible ocean meteorological observation unmanned vessel, and launched a sounding rocket on the unmanned vessel for the first time; The real-time marine meteorological observation data, sea surface temperature and the temperature, humidity, air pressure in the marine boundary layer, as well as the vertical profiles of wind speed and direction are obtained. The success of a series of river and sea tests shows that this semi submersible has no protection and long service life. The structural design of the hull, combined with automatic navigation control, real-time satellite data communication, automatic meteorological and hydrological observation, and sounding rocket launch, enables the boat to operate at a long distance Changhangshi and Henan Yicheng Hanbo Energy Technology Co., Ltd. (hereinafter referred to as Yicheng Hanbo), a special subsidiary of Yicheng Xinneng, are responsible for the above 10000 ton cathode material project under complex sea conditions, and can carry out continuous and real-time sea surface meteorological observation, meteorological sounding, real-time data and instruction transmission, and working state monitoring in the middle and lower troposphere; It can realize the fixed-point or navigational detection of marine meteorological and hydrological elements, especially in the open sea. As a mobile automatic weather station and sounding station that can be deployed and recovered independently on the sea, the functions of real-time monitoring the sea are introduced as follows: 1) automatic shutdown: after the sample is broken, it will go up the weather such as strong wind, fog and thunderstorm, and monitor the sea temperature, sea salt and current parameters at the same time, so as to provide data for the business and scientific research of Marine Meteorology and hydrology. These ocean meteorological observation data can promote the research of air sea interaction, the estimation of sensible and latent heat fluxes at the air sea interface, the simulation of ocean boundary layer and the verification of ocean satellite products
