Abstract
Nested in the lap of mighty Himalayas, the Indian state of Uttarakhand is climatologically very sensitive and ecologically fragile. Owing to its natural beauty, religious tone and rich biological succession the state is known as Land of Gods’ and ‘land of austerity. However, increasing population pressure is posing a great challenge to the natural harmony of this vulnerable state. During recent years the state has recorded a significant increase in climatological disasters and for that the humanogenic enhancement of regional atmospheric entropy is being seen as the cause. Present paper analyses temperature and rainfall changes that the state has witnessed during the last century. The study is mainly based on the district temperature and rainfall series of 102 years obtained from India Meteorological Department.
Highlights
Uttarakhand, one of the 12 Himalayan states of India, is known for its natural beauty and highly varied physiography
Climate is a self-balancing robust system that is capable to manage small changes due to its chaotic nature it goes random at some stage in course of its management cycle
This random state speaks about the unexpected shifts in the climate. Such big shifts which are nothing but the accumulation of small changes often result into a catastrophe. Keeping in mind this chaotic nature of climate system, it is, necessary to monitor every pulse of climate, if our existence really matters [2,3]
Summary
Nested in the lap of mighty Himalayas, the Indian state of Uttarakhand is climatologically very sensitive and ecologically fragile. Increasing population pressure is posing a great challenge to the natural harmony of this vulnerable state. During recent years the state has recorded a significant increase in climatological disasters and for that the humanogenic enhancement of regional atmospheric entropy is being seen as the cause. Present paper analyses temperature and rainfall changes that the state has witnessed during the last century. The analysis reveals that the state has recorded a significant increase in temperature while the volume of rainfall it receives annually, has declined during the course of the last century. The monthly changes show that the state is losing its seasonal contrast, and while winter months are becoming warmer, monsoon months are losing their heat and the quantum of rainfall
