How Rainfall is measured ⁉⛈️🌨️
Rainfall is measured by the instrument called rain gauge. Rain water collected in this gauge is measured in millimetres or inches.
Rainfall is measured in litres per square meter which is equivalent to mm and can be conveniently converted to meter or cm.
A Rain Gauge is placed 30 cm above the ground in an open area where there are no trees or buildings to block the rain, and where only rainfall can enter the rain gauge. The rain collected in the rain gauge is usually measured every morning with a measuring cylinder at a fixed time. The measurement constitutes the daily rainfall and is recorded in millimetres(mm). By adding up the amount of rain collected in a month, we get the monthly
rainfall. The total amount of rainfall collected over 12 months is the annual rainfall.
The main conversion factor is 1 mm of rainfall = 1 Liter of water/m² (or 0.001 m³ of water/m²);
Here m² means Meter square
The intensities of rain rate are:
up to 5 mm/hr = Light rain rate
between 5–10 mm/hr = Moderate rain rate
10 to 50 mm/hr = Heavy rain rate
50 to 100 mm/hr = Very heavy rain rate
100 to 200 mm/hr = Extreme moderate rain rate
> 200 mm/hr = Extremely high / cloud burst
😳Why❓❓❓
Why Tiger is selected as National Animal and why not Lion or other animals?
It was selected as a national animal because of its presence in larger parts of the country. It is found in 16 states while the lion is found only in one state. the Bengal tigers of India are epitomes of great courage, power and sharp intelligence. They have hunted down elephants and crocodiles too, although this is rare, and they do it all alone.
You might be aware that tigers are not only the largest, but also the strongest of big cats (YES, tiger is stronger than a lion, because tiger not only has a higher muscle density of 72.6%, compared to lion’s 58.8%, but tigers also keep themselves very active by walking great distances, hunting difficult prey all alone, swimming miles and miles, and in India, occasionally climbing very tall trees, too. This keeps up their muscle strength. Lion mostly sleeps).
