The Indian Meteorological Department was set up in 2000.
Hygrometer is used to measure humidity.
The motto of the Indian Meteorological Department is “Adityat Jayate” ______.
The Indian Meteorological Department was set up in the year ______.
The unit used to measure atmospheric pressure is ______.
Atmospheric pressure is measured using a ______.

If the humidity in Delhi is at 52% while in Kochi it is 84% in which of the two places are wet clothes likely to dry faster? And where are you likely to sweat more, assuming the temperature in the same in both places?
Discuss in pairs, different situations in which weather predictions are useful. Make a list and after you have completed your list, share it and discuss it with the pair sitting next to you. How many different categories of situations have you been able to identify?
Where do you think the humidity is likely to be more, Kochi or Jaipur? You might guess that Kochi has higher humidity than Jaipur because it is located near the sea. But how will we know for sure? If we had to compare the humidity level between Kochi and Mangaluru, how would we do it? Discuss with your classmates.
Make a rain gauge as shown in the below diagram. Place the rain gauge in an open area, away from objects that might obstruct rain. Ensure that the rain gauge is on a flat surface and will not tilt or topple with the wind. Using the measuring scale, record the amount of rainwater collected at the same time every day, for a month. (If there is snow, allow it to melt before taking the measurement.) Calculate the average rainfall for every week in that month and comment on the variation from week to week.
Here’s a chart of the temperatures of a city in Madhya Pradesh. What is the maximum temperature recorded in the week shown here? What is the minimum temperature? Calculate the range.
| Date | Maximum Temperature (in °C) | Minimum Temperature (in °C) |
| 28.02.2025 | 29 | 16 |
| 01.03.2025 | 30 | 15 |
| 02.03.2025 | 31 | 17 |

Have you seen seeds like these flying in the wind (see the below image)? What would happen to the seeds if there was no wind?
Let us imagine Krishnan from Chennai is speaking with Amir in Kashmiri. Krishnan tells Amir that it has become chilly in Chennai after it rained the previous night. Amir asks him how cold it is. How will Krishnan explain to Amir how cold it is? After all, what is cold for Krishnan may not be cold for Amir?
Remember the conservation between Krishnan and Amir? If Krishnan said it was 20 degree Celsius in Chennai and that he was feeling a little cold, both he and Amir would have a measure they could understand. What do you think Amir’s reaction to Krishnan’s statement might be?
Imagine that a small group of students is setting up a rain gauge. Here are some options for the site.
(i) The school vegetable garden.
(ii) The terrace of the school building.
(iii) Open ground with elevated platform.
(iv) Compound wall of school.
(v) Verandah of the school laboratory.
Discuss in your group and finalise the site. Write down the reasons for your decisions.

Jyotsna is deciding what clothes to pack for her school trip to Mumbai in June. She looks at the weather forecast, which predicts 29°C and 84% humidity. What would be your advice to her?
Match the instrument with the weather element it measures.
| Instrument used | Element of the Weather |
| 1. Hygrometer | (a) Precipitation |
| 2. Anemometer | (b) Atmospheric pressure |
| 3. Barometer | (c) Wind direction and speed |
| 4. Thermometer | (d) Humidity |

People who journey to places at a high altitude are advised to make pause on the way to allow the body to acclimatise. Our army personnel serve in high- altitude places like Khardungla in Ladakh, which is over 5600 metres above sea level. It is hard to image how they live and work in places where the oxygen level is so low – the atmospheric pressure there is generally about 650 millibars!
