Introduction

Air refers to the Earth's atmosphere. Air is a mixture of many gases and tiny dust particles. It is the clear gas in which living things live and breathe. It has an indefinite shape and volume. It has mass and weight, because it is matter. The weight of air creates atmospheric pressure. There is no air in outer space.
Air is a mixture of about 78% of nitrogen, 21% of oxygen, 0.9% of argon, 0.04% of carbon dioxide, and very small amounts of other gases. There is an average of about 1% water vapour.
Since early times, air has been used to create technology. Ships moved with sails and windmills used the mechanical motion of air. Aircraft use propellers to move air over a wing, which allows them to fly. Since the late 1900s, air power is also used to generate electricity.
Air is invisible: it cannot be seen by the eye, though a shimmering in hot air can be seen.
Air is one of the four classical elements in Greek theory. It was considered an intervening element, somewhere between fire and water, and the driving force for the birth of the cosmos.
We have chosen two places- Srinagar and Chennai. So now lets know about them but before that lets know the difference between surface temperatures and precipitation types.
Difference between Surface Temperatures and Precipitation Types
Forecast Maps
What is Forecast Map?
Forecast map also known as synoptic weather chart, displays various meteorological features across a particular area at a particular point in time and has various symbols which all have specific meanings. Such maps have been in use since the mid-19th century and are used for research and weather forecasting purposes. Maps using isotherms show temperature gradients, which can help locate weather fronts. Isotach maps, analyzing lines of equal wind speed, on a constant pressure surface of 300 or 250 hPa show where the jet stream is located. Use of constant pressure charts at the 700 and 500 hPa level can indicate tropical cyclone motion.

Climate
What is Climate?
The average weather condition of a place for a longer period of time represents the climate of a place. Climate is statistical weather data that gives information about the average weather condition of a specific place over a long period. The climate is the long term observances of the atmospheric situations at any area like humidity, temperature, the sunshine, wind, etc.

Climate of Srinagar-
Srinagar has a humid subtropical climate (Köppen Cfa). The valley is surrounded by the Himalayas on all sides. Winters are cool, with daytime temperature averaging to 2.5 °C (36.5 °F), and drops below freezing point at night

Climate of Chennai-
Chennai mostly experience a tropical wet and dry climate. Chennai lies on the thermal equator which prevents extreme variation in seasonal temperature. For most of the year, the weather is hot and humid.The coolest part of the year is January, with minimum temperatures around 18–20 °C (64–68 °F). The temperature in Chennai in summer's are 37°C - 27°C. The highest temperature of Chennai during summer is 41°C and the lowest temperature goes upto 20°C.
