Answer 1

Hint: Every place experiences annual rainfall that would be calculated based on the monthly rainfall. As seasons change, the amount of rainfall received in a particular place also changes.

Complete answer:
There is some data provided in the table. The monthly rainfall of every month and the temperature of every month are given. The temperature is given in $^\circ {\text{C}}$ and rainfall in given in terms of cm. The temperature in January is $23.1^\circ {\text{C}}$ , in February it is $24.8^\circ {\text{C}}$ , in March it is $26.5^\circ {\text{C}}$ , in April it is $29.3^\circ {\text{C}}$ , in May it is $32^\circ {\text{C}}$ , in June it is $32.8^\circ {\text{C}}$ , in July it is $33.1^\circ {\text{C}}$ , in August it is $32.1^\circ {\text{C}}$ , in September it is $30.5^\circ {\text{C}}$ , in October it is $29.3^\circ {\text{C}}$ , in November it is $28.7^\circ {\text{C}}$ and in December it is $26.1^\circ {\text{C}}$ . Coming to the rainfall, in January the amount of rainfall is $15.3$ cm, in February it is $10.1$ cm, in March it is $0.3$ cm, in April it is $0.1$ cm, in May it is $1.3$ cm, in June it is $4.5$ cm, in July it is $6.1$ cm, in August it is $10.2$ cm, in September it is $10.5$ cm, in October it is $20.1$ cm, in November it is $16.8$ cm and in December it is $19.0$ cm. This is the given data.
The annual rainfall experienced by the station would be calculated by adding every month rainfall in a year. Every year has twelve months.
${\text{The annual rainfall experienced by the station (in cm)}} = 15.3 + 10.1 + 0.3 + 0.1 + 1.3 + 4.5 + 6.1 + 10.2 + 10.5 + 20.1 + 16.8 + 19.0 = 114.3{\text{ cm}}$
Therefore, the annual rainfall experienced by the station is $114.3$ cm.
The best name for the station would be the name of the place as people could identify the station easily and it would be better for understanding and easy to implement any projects.
The season during which the rainfall is heaviest is the rainy season. This season is from July to Mid-September.

Note: Rainy season is also known as the monsoon. While calculating the annual rainfall, only add every month’s rainfall. This total should not be divided by the number of months in a year as the result would be the average rainfall. Do not confuse between the annual rainfall and the average rainfall.
