Generally some vertical meteorological observations are made by towers, radars, balloons and so on. Captive balloons are used because it is easy to use in urban area. Conventional balloons are influenced by the wind and lean. It is dangerous to observe in urban area because there are high buildings. Therefore we have developed a new type of captive balloon. Wing form is a characteristic of it. This form makes lift, and the balloon hardly leans. It was found that the third balloon we were making is separated from air through CFD analysis. We changed to the fourth it which is flatter than the third. We made wind tunnel test with 1/10 model of it. It shows that maximum lift/drag ratio is 5, moreover, that the angle of 13.5 degrees is stability. These are enough to gain the lift and certify to achieve our aims.
