Because helium (He) is lighter than air and not flammable like Hydrogen (H) which is the lightest element.
Helium is safer than hydrogen in hot air balloons because it is non-flammable. Hydrogen can ignite easily, posing a greater risk of fire. Additionally, helium is more stable and its lifting capacity is sufficient for use in hot air balloons.
Contemporary weather balloons are usually filled with helium. Helium is lighter than air, and this allows the balloon to rise as this gas is lighter than air.Hydrogen would also work as it has a low density, like helium. And hydrogen is a bit cheaper than helium because it can be "made" from water. But hydrogen is flammable or even explosive, and it is generally not used for that reason.
Weather balloons can be equipped with white, green, or red navigational lights for nighttime visibility. These lights help aircraft and other observers spot the weather balloon in the dark.
They throw meteors at people They predict the weather with barometers, squeeglyspooches weather balloons, etc.
Hydrogen is used in weather balloons because it is a very lightweight gas that provides the necessary buoyancy to lift the balloon and its payload to high altitudes. It is also readily available and less expensive compared to other gases like helium.
forcasting is predicting the weather. Weathering is tempering the weather

weather balloons are instruments that study the weather
Weather balloons are traditionally filled with hydrogen due to its low density and cost-effectiveness. However, helium is a safer alternative because it is non-flammable. The choice between hydrogen and helium depends on safety considerations and budget constraints.
Meteorological balloons are made from natural latex rubber, mostly in Japan.
It's equal!!
Weather balloons are typically filled with helium or hydrogen gas to provide buoyancy and lift the instrument package into the atmosphere. Helium is the most commonly used gas because it is non-flammable and more stable than hydrogen.
They Do Not use Hydrogen gas to fill up balloons. People use Helium gas to fill up balloons (ordinary party balloons, and big working balloons such as the one used by Goodyear). Helium is Not Flammable. Hydrogen is Flammable and has as tendency to burst into Flame, similar to the German Blimp/Dirigible Hindenburg. Since the US Navy lost Two Helium Blimps in Bad weather; The Akron and the Shenandoah (with a great loss of lives), the US Navy almost never uses Blimps anymore.
the weather tomorrow is going to be cold. or the weather is forcasting 4 to 8 inches of snow or the weather is nice today
the practice of modern weather forcasting and the electomagnetic resonance
