this is because it is the lightest known substance,about 14.4 times less densn than air.
Meteorological balloons are made from natural latex rubber, mostly in Japan.
Hydrogen is too flammable
Hydrogen was one of the earliest gases to be used for inflatable flying balloons, but following the Hindenberg disaster helium is now used, as it is chemically inert.
Helium is used in balloons because it is much less dense than air, allowing the balloons to float and is completely nontoxic and nonflammable unlike hydrogen, which is otherwise a superior lifting gas.

Weather balloons are sometimes used to obtain meteorological data from high altitudes.

Hydrogen is too flammable
Hydrogen is used in weather balloons because they are very light which help the balloon to float or fly easily.
The Meteorological balloons manufactured from natural rubber latex by our factory are used to detect air basic factors in natural environment. It has two types, one is wind-cloud-detecting Meteorological balloon and the other is sounding balloon. It acts as carrying tools used widely in Meteorological detecting. It is one important and necessary tool to develop Meteorological science, aviation, interspace technology. The Meteorological balloon follows GJB1961-94 standard issued by The Military Standard of P.R.C. in quality, specification, packing.
Just a met balloon - meteorological balloon. Generally filled with hydrogen.
Helium is used instead of hydrogen because it is nonflammable.
Helium is used in blimps and balloons. It is the second lightest element to hydrogen, which is not used because it is highly flammable.
Hydrogen
Two of the gases that are used to fly balloons are Hydrogen and Helium. Helium is the preferred gas because Hydrogen is very explosive. The Hindenburg disaster was caused by the ignition of the Hydrogen gas that filled it.
