Domestic large-scale UAV drilled into Typhoon 'Paibian', the first domestic typhoon multi-aircraft platform joint observation was successful

News from this site on July 24. According to official news from the China Meteorological Administration, at 2:45 on July 21, at the Boao National UAV Meteorological Observation Test Base in Hainan, the "Haiyan" Type I UAV penetrated clouds and fog. , drilling into this year's No. 4 typhoon "Paibian"; at 10 o'clock, the Hong Kong Observatory's manned aircraft joined the detection formation to conduct detection and scanning of "Paibian". This is the first time that the China Meteorological Administration and the Hong Kong Observatory have jointly observed a typhoon from multiple aircraft platforms and multiple sensitive areas, accurately capturing the cloud structure around Paibian.

After two hours of flight, the "Haiyan" Type I UAV returned at 4:45, and transmitted more than 4,200 pieces of valid data captured to the meteorological big data cloud platform "Tianqing" system in real time, and provided To the Central Meteorological Observatory, China Meteorological Administration Earth System Numerical Prediction Center, China Meteorological Administration Guangzhou Tropical Marine Meteorology Institute, China Meteorological Administration Shanghai Typhoon Research Institute and other units.

At 10:00, the Hong Kong Observatory and the Government Flying Service used manned aircraft to carry dropsondes to conduct dropdown observations in the relevant airspace.

This time, the "Haiyan" I drone accurately dropped 8 sondes at a set time and location, recording data such as temperature, humidity, wind direction, wind speed, and air pressure at different altitudes, allowing for a more three-dimensional observation of "Pei" Bian” three-dimensional structure. At the same time, the cloud radar, temperature and humidity profiler and other equipment it carried for the first time obtained information such as cloud echo reflectivity, velocity spectrum, temperature, humidity and other information on the passing typhoon when it passed through "Pebian". The data on the structure or surrounding environment field is detailed and clear, allowing forecasters to clearly "see" the distribution and structure of the typhoon cloud system in real time, thereby more scientifically grasping the development of the typhoon.

This site learned from the official platform of the China Meteorological Administration that the center of this year's No. 4 typhoon "Paibian" (severe tropical storm level) was located at 5 o'clock in the morning on July 23 offshore Quang Ninh Province, Vietnam, at 21.3 North Latitude degree, east longitude 107.7 degrees, the maximum wind force near the center is level 10 (25 meters/second), the minimum air pressure at the center is 988 hPa, and the radius of the level 7 wind circle is 60-120 kilometers. Subsequently, the intensity of the weakened tropical depression "Paibian" further weakened, and it is now difficult to determine its circulation center. The Central Meteorological Observatory stopped numbering it at 20:00 on July 23.

In addition, the Central Meteorological Observatory issued a typhoon red warning at 10:00 on July 24: Typhoon No. 3 "Gemei" this year will strengthen from a strong typhoon level to a super typhoon level at 8 a.m. today (24th) at 9 a.m. Its center is located on the ocean about 195 kilometers southeast of Yilan County, Taiwan Province, my country.

"Gemei" is expected to move northwest at a speed of 10-15 kilometers per hour, with little change in intensity or slightly stronger intensity. It will make landfall on the coast from Hualien to Keelung, Taiwan Province tonight (strong typhoon level or super typhoon level) Severe typhoon level, level 15-16, 48-52 m/s). After that, it will pass through Taiwan Island and will make landfall on the coast from Fuding to Jinjiang, Fujian Province from tomorrow afternoon to night (typhoon level or severe typhoon level, level 12-14, 33-42 meters/second). Then it goes deep inland and moves northward, gradually weakening in intensity.
