Weather Forecast: How does IMD know the weather of the coming days, know which technology works behind it.


The weather department gives you all the news whether it will rain, hail, cold or the temperature will rise in your city or where you have to go. Because the weather department already makes predictions about the weather for the coming days. Most people decide their programs keeping the weather in mind. But the question is, how does the Meteorological Department get this information? After all, what technology works behind this. 

Meteorological Department

Let us tell you that many factors are responsible for weather forecasting. Are there. For this, with the help of various instruments, the temperature of the atmosphere and ground surface, humidity, wind speed and direction, dew, condition of clouds etc. are observed. Many types of machines and equipment are used for this. Such as rain gauge for rain, anemometer for measuring wind speed, wind vane for wind direction, pen-evaporimeter for measuring the rate of evaporation, sunshine recorder, dew gauge for dew, thermometer for measuring ground temperature etc. Is used. 

Apart from this, high-speed computers, meteorological satellites, air balloons and weather radars also play an important role in gathering weather data. After this the data collected is studied and the current data and past data of the weather are also seen. After this the weather is predicted. 

Satellite

According to the information, the Meteorological Department has many types of satellites. Who keep sending pictures of clouds. Due to this, the people of the weather department keep guessing where there are clouds and where there are not. However, looking at the clouds only gives an idea of ​​where the sun will shine and where it is expected to be cloudy. To estimate rainfall, one has to see how much water is present in the clouds. For this, radar is launched from the earth towards the sky. The waves sent through radar bounce back from the clouds and are then studied. After this, the weather department predicts where it may rain.

Amount of rain

You must have often heard that this much rainfall occurs in this city. Mm it has rained. Actually, the Meteorological Department has a bucket-shaped funnel, which is kept at a place where there are neither any big buildings nor any trees. This means that when rain water falls, the funnel can be filled properly. Numbers are written in MM in this key. Let us tell you that these numbers are seen after the rain stops, on the basis of this the Meteorological Department releases how many mm of rain has occurred at which place.

Weather Prediction /p>

The weather department makes 4 types of predictions. First immediate which is for next 24 hours, second short term which is for 1 to 3 days, third medium term which is for 4 to 10 days and fourth extended term which is for 10 Happens for more than 100 days. Of these, medium term predictions are seen to be mostly correct. Which people generally call the forecast of the coming 7-8 days.
