Horizontally floating balloon with controllable height and working process thereof

The invention discloses a horizontally floating balloon with a controllable height and a working process thereof in the field of meteorological detection. The horizontally floating balloon comprises ahorizontally floating balloon body, a deflator, a load releaser and a sonde. The deflator is connected to the horizontally floating balloon body to release gas in the horizontally floating balloon body when the horizontally floating balloon rises, the load releaser is connected to the horizontally floating balloon body to release a load when the horizontally floating balloon goes down, and the sonde is connected to with the horizontally floating balloon body to collect meteorological elements. A sounding balloon is controlled through the deflator and the load releaser to realize horizontal floating, a defect that a horizontally floating sounding weather balloon continuously ascends or descends and a horizontally floating function can not be achieved caused by inaccurate and inappropriatenet lifting force, balloon
