China launches weather rocket from a drone sub ingroundbreaking step toward ocean-wide networks that can monitor hurricanes fromINSIDE the storms

中国从无人潜艇上发射气象火箭,这是中国向建立全海洋网络迈出的突破性的一步,将可从风暴内部监测飓风



Scientists in China have launched a weather observation rocket from asemi-submersible drone ship in a world's first for meteorological research.

中国科学家从一艘半潜式无人艇上发射了一枚气象观测火箭用于气象研究,这属于世界首创。

The unmanned semi-submersible vehicle (USSV) was designed specifically todeploy instruments that can hit altitudes beyond the reach of weather balloons.

这种半潜式无人艇(USSV)发射的仪器所能抵达的高度比气象气球更高。



‘The unmanned semi-submersible vehicle is an ideal platform for marinemeteorological environmental monitoring, and the atmospheric profileinformation provided by rocketsonde launched from this platform can improve theaccuracy of numerical weather forecasts at sea and in coastal zones,' explainsstudy co-author Dr Jun Li, a researcher at the Institute of AtmosphericPhysics.

该研究的合著者、大气物理研究所研究员李俊博士解释称道:“半潜式无人艇是海洋气象环境监测的理想平台,从该平台发射的火箭探空仪提供的大气廓线信息,可提高海洋和沿海地区数值天气预报的准确性。”

‘Similar to Argo (the broad-scale global array of profiling floats thatmeasures temperature/salinity in the ocean) which provides profiles ofThermohaline current, rocketsonde can provide profiles of atmospherictemperature, humidity, pressure and wind observations.'

“与ARGO(大范围收集全球海洋上层的海水温、盐度剖面资料)提供温盐海流剖面资料类似,气象火箭也可以提供大气温度、湿度、压力和风的观测剖面资料。”

The team plans to develop a network of unmanned semi-submersible vehiclesacross the oceans to match that on land.

该小组计划开发一个横跨海洋的无人驾驶半潜式飞行器网络,以与陆地上的网络相匹配。

The main problem with climate models is uncertainty.

气候模型的主要问题是不确定性。

In particular, something called the 'equilibrium climate sensitivity' measurehas been causing scientists a headache.

特别是,“平衡气候敏感度”的测量一直让科学家头疼。



These vehicles themselves could be built to contain sensors that would allowfor three-dimensional observations from inside typhoons and hurricanes.

这些飞行器本身可以安装传感器,以便从台风和飓风内部进行三维观测。

‘We are currently developing a new generation of USSVs which can carry varioussensors relevant to marine science, including conductivity-temperature-depth,acoustic Doppler current profiler, and motion sensors to provide verticalprofiles of the conductivity, water temperature, current velocity, and waveheight and direction,' Chen says.

“我们目前正在开发新一代半潜式无人艇(USSV),它可以携带与海洋科学相关的各种传感器,包括传导温度深度、声学多普勒电流剖面仪和运动传感器,以提供传导率、水温、流速、波高和方向的垂直剖面。”

‘With that, a new interconnected USSV meteorological and oceanographic (METOC)observation network system will be developed to improve the efficiency ofcollecting METOC observations and provide comprehensive data at the temporaland spatial scales required to answer relevant scientific questions.'

“在此基础上,我们将开发一个新的互联的USSV气象与海洋学(METOC)观测网络系统,以提高收集气象和海洋观测数据的效率,并在时间和空间尺度上提供回答相关科学问题所需的全面数据。”
