Nagpur: To forecast weather, large balloons are released in the sky every day. These are called ‘Weather Balloon’. From this, the temperature including rain is estimated. This experiment has been done 2 times a day for many years to predict the weather by the Meteorological Department. Balloons are released into the sky in the morning and 4.30 in the evening.
These balloons go about 50 kilometers in the sky. This thing can surprise anyone but it is completely true. The balloon automatically grows up after going into the sky and bursting after some time. However, by then the Meteorological Department gets accurate information of the weather with the help of a balloon - devices.
The weather forecast is released by the Meteorological Department after obtaining information in the air division, ie the upper layer of the sky, the speed of the air, the direction of the air and the moisture in the air. These special balloons are released into the sky by all the meteorological departments across the country to monitor the weather. This is called ‘radiosond’.
The balloon is equipped with important sensors and GPS systems. With this, the Regional Meteorological Department gets accurate information till the last moment. These balloons are an important tool for weather prediction. These balloons also help in studying changes in the air division.
Experts said that from the year 1967, balloons are released in the sky twice a day by the Nagpur Territorial Meteorological Department. These balloons have hydrogen gas filled. The main reason for this is that the weight of hydrogen gas is lighter. A 750 gram balloon is released in the sky at 4 am, while a 350 gram balloon is left at 4.30 pm. Balloons are released into the sky only after following the instructions of meteorological standards.
The balloons released by the Meteorological Department have different weight. Because of this they fly to different heights. The balloon released in the morning usually flies from 40 to 50 kilometers. The reason is that the weight of that balloon is 750 grams. Because of this the balloon goes to higher height. At the same time, the balloon released in the evening runs with hydrogen gas weighing 350 grams. Because of this, it usually fly from 30 to 40 kilometers.
According to experts, the balloon has thermistor, GPC and important sensor devices. This gives the Meteorological Department information about the weather with the help of antenna sensor and GPS. The information is then decoded after which the weather forecast is expressed. The balloon gets bigger after going into the sky. After reaching a certain shape, it burst and the device in it falls into the surrounding forest, river, lake or human settlements.

The cost of leaving a balloon in the sky is usually around 12,000 to 15,000 rupees. The cost of 2 balloons per day ranges from around 25,000 to 30,000 rupees. The first pilot balloon observation was predicted by the weather. This used to provide information about the speed of the wind and the direction of the wind. However, now as an updated version, the radio wind (radiosond) technique is giving accurate information about air conditions, air speed, air direction, temperature and humidity in the air.
