The polar tundra climate is characterized by cold winters, cool summers, and a summer rainfall regime. This climate is divided into following three sub types. Critchfield, General Climatology, 4th ed. Used for C and D climates. Daily highs are about 32° Celsius, while night time temperatures average 22° Celsius.
The annual rainfall varies here from 62. The average diurnal range is from 14 to 25° Celsius. Mild Humid Climate with a dry summer Cs : Temperate rainy climate with dry summer. Summers are very hot, while in winters, temperature can plunge to as low as 0°C. Most of the Himalayan region including Jammu and Kashmir, Himachal Pradesh, Uttaranchal, Sikkim and Arunachal Pradesh has this climate.
January and July temperatures are 12°-27°C and 26°-34°C respectively. This climate is suitable for grasslands. Precipitation of the wettest month of winter is at least 3 times as much as that of the driest month of summer or 70% or more of the mean annual precipitation falls in the six months of winter. The average temperature of the warmest month is greater than 10° Celsius, while the coldest month is less than -3° Celsius. So it is known as tl1 famine zone of India. Areas having water surplus in all the months of the year have a humid climate and areas having water deficit in all the months of the year have an arid climate. The Temperate or Continental India has been divided into following five regions: 1.
Climatic Region Descriptions The following discussion organizes the climatic regions of the world into eight different groups. Archived from on 24 December 2018. Continental Polar air masses are associated with cold, dry weather conditions. About 75% of the total rainfall of the country is supplied by the monsoon torrents during this season. This procedure may seem to be of fundamental inconsistency. It accepts the native vegetation as the best expression of the totality of a climate, so that many of the climatic boundaries are based upon vegetation.
This modifier is applied to A, C and D groups, yielding combinations — Af, Cf and Df. Three minor Köppen climate types exist in the A group, and their designation is based on seasonal distribution of rainfall. If it is more than the need, then there is a surplus. In the Himalayas where the southern slopes are protected from cold, northerly winds accessible to the south-west monsoons, there is heavy rainfall on the slopes which are at a height of 1,069-2,286 m above sea level. Sub-tropical arid desert climate The whole of the covering most of excluding the eastern and southern fringes , and the of Western falls under this climate type characterised by scanty rainfall.
The climates have no true summer. These climates occur only in eastern. The months of December to February are excellent times to make a trip to South India. In contrast, type H climate contains all highland areas not easily categorized by other climate types. Towards the north of the summer monsoon is responsible for most of the rainfall, while to the south of the river rainfall also occurs in the months of October and November. Winters are very cold and rainfall is scanty.
Cs - Santiago, Chile 33. It is important to understand this concept because of its climatic ramifications for locations on the globe. Thornthwaite evolved a formula to work out the monthly values of water surplus and water deficit. This region receives an annual rainfall of 250 cm. The average temperature is above 27°C but the rainfall is below 100 cm. The Arabian Sea branch extends towards the low-pressure area over Thar Desert and is about three times stronger than the Bay of Bengal branch.
Coastal regions of Odisha, West Bengal, Tamil Nadu and Andhra Pradesh are more exposed to cyclones. Rainfall is comparatively low because this region lies in the rain shadow area of the Western Ghats. B - Dry Climates: with deficient precipitation during most of the year. In 1990, Wladimir Koppen published the first climate classification scheme. It also extends into Rajasthan east of the Aravalli range.
The Köppen climate classification system has been further modified, within the system in the middle 1960s revised in 1980. Annual range of monthly temperatures is about 3° Celsius. If the rainfall of a place is less than the water which is lost through evaporation and transpiration, the place has a water deficit. The summers are hot and temperatures can reach 46 °C in the lowlands. Summer weather is dominated by Maritime Tropical which produce many from daytime heating.
The nation has four seasons: winter January and February , summer March to May , a monsoon rainy season June to September , and a post-monsoon period October to December. All other temperatures are monthly means °C , and all other precipitation amounts are mean monthly totals mm. Hot desert type Bwhw 6. Adequate precipitation in all months. This region receives and annual rainfall of 100 cm and the mean maximum temperature here is 45° C and the mean minimum temperature is 18° C.
