  3. Introduction India is home to an extraordinary variety of climatic regions, ranging from tropical in the south to temperate and alpine in the Himalayan north, where elevated regions receive sustained winter snowfall The nation's climate is strongly influenced by the Himalayas and the Thar Desert. The Himalayas act as a barrier to the frigid katabatic winds flowing down from Central Asia keeping the bulk of the Indian subcontinent warmer than most locations at similar latitudes. . As such, land areas in the north of the country have a continental climate with severe summer conditions that alternates with cold winters when temperatures plunge to freezing point.

  4. Seasons in India

  5. Season Characteristics Note Winter or cold weather season clear skies, fine weather, light The cold air mass northerly winds, low humidity and temperatures, and large daytime variations of temperature extending from the Siberian region, during these months. The mean air temperatures increase from north to south up to 17 N, the decrease being sharp as one moves northwards in the north- western parts of the country. . The mean temperatures vary from 14 C to 27 C during January The rains during this season generally occur over the western Himalayas, the extreme north-eastern parts, Tamil Nadu and Kerala

  6. Floods

  7. Floods are caused by the inadequate capacity within the banks of the rivers to contain the high flows brought down from the upper catchment due to heavy rainfall In coastal areas, they are caused by cyclones and typhoons. Other causes include backing up of waters in tributaries at their outfalls into the main river often with synchronization of floods in them; ice jams or landslides blocking stream courses resulting in the backwater overflowing river banks. Flash flood occurs in areas near foot hills. However the root cause of flood is excessive rainfall which occurs mainly in the monsoon months of July to September. Floods are also sometimes caused by Glacial Lake Outburst called Glacial Lake Outburst Floods (GLOFs) which can be catastrophic for people living immediately downstream and can cause serious damage to infrastructure and the economy

  8. The flood problem in India is mostly confined to the states located in the Indo Gangetic plains, northeast India and occasionally in the rivers of Central India Heavy rainfall, inadequate capacity of rivers to carry the high flood discharge, inadequate drainage to carry away the rainwater quickly to Streams/ Rivers, storm surges, Man made factors such as failure of dams and other control works like reservoirs are the main causes of floods Ice jams or landslides blocking streams, debris flow, back water, and cyclones also cause floods. Excessive rainfall combined with inadequate carrying capacity of streams resulting in over spilling of banks is the cause for flooding in majority of cases
