Hydrology

Despite their scale, the Himalayas do not form a major watershed, and a number of rivers cut through the range, particularly in the eastern part of the range. As a result, the main ridge of the Himalayas is not clearly defined, and mountain passes are not as significant for traversing the range as with other mountain ranges. The rivers of the Himalayas drain into two large river systems: * The western rivers combine into the ''Indus Basin''. The Indus itself forms the northern and western boundaries of the Himalayas. It begins in Tibet at the confluence of Sengge and Gar rivers and flows north-west through India into Pakistan before turning south-west to the

The higher regions of the Himalayas are snowbound throughout the year, in spite of their proximity to the tropics, and they form the sources of several large perennial rivers. In recent years, scientists have monitored a notable increase in the rate of glacier retreat across the region as a result of climate change. For example, glacial lakes have been forming rapidly on the surface of debris-covered glaciers in the Bhutan Himalaya during the last few decades. Although the effect of this will not be known for many years, it potentially could mean disaster for the hundreds of millions of people who rely on the glaciers to feed the rivers during the dry seasons. The global climate change will affect the water resources and livelihoods of the Greater Himalayan region.

glacier lake in the Rowaling Valley, in the Dolakha District of Nepal, is rated as the most dangerous. The lake, which is located at an altitude of has grown considerably over the last 50 years due to glacial melting. The mountain lakes are known to geographers as '' tarns'' if they are caused by glacial activity. Tarns are found mostly in the upper reaches of the Himalaya, above . Temperate Himalayan wetlands provide important habitat and layover sites for migratory birds. Many mid and low altitude lakes remain poorly studied in terms of their hydrology and biodiversity, like Khecheopalri in the Sikkim Eastern Himalayas.


Climate


Temperature

The physical factors determining the climate in any location in the Himalayas include latitude, altitude, and the relative motion of the Southwest monsoon. From south to north, the mountains cover more than eight degrees of latitude, spanning temperate to subtropical zones. The colder air of Central Asia is prevented from blowing down into South Asia by the physical configuration of the Himalayas. This causes the tropical zone to extend farther north in South Asia than anywhere else in the world. The evidence is unmistakable in the Brahmaputra valley as the warm air from the

bottlenecks and rushes up past Namcha Barwa, the eastern anchor of the Himalayas, and into southeastern Tibet. Temperatures in the Himalayas cool by 2.0 degrees C (3.6 degrees F) for every increase of altitude. As the physical features of mountains are irregular, with broken jagged contours, there can be wide variations in temperature over short distances. Temperature at a location on a mountain depends on the season of the year, the bearing of the sun with respect to the face on which the location lies, and the

of the mountain, i.e. the amount of matter in the mountain. As the temperature is directly proportional to received radiation from the sun, the faces that receive more direct sunlight also have a greater heat buildup. In narrow valleys—lying between steep mountain faces—there can be dramatically different weather along their two margins. The side to the north with a mountain above facing south can have an extra month of the growing season. The mass of the mountain also influences the temperature, as it acts as a heat island, in which more heat is absorbed and retained than the surroundings, and therefore influences the heat budget or the amount of heat needed to raise the temperature from the winter minimum winter to the summer maximum. The immense scale of the Himalayas means that many summits can create their own weather, the temperature fluctuating from one summit to another, from one face to another, and all may be quite different from the weather in nearby plateaus or valleys.


Precipitation

A critical influence on the Himalayan climate is the Southwest Monsoon. This is not so much the rain of the summer months as the wind that carries the rain. Different rates of heating and cooling between the Central Asian continent and the South Asian ocean create large differences in the atmospheric pressure prevailing above each. In the winter, a high-pressure system forms and remains suspended above Central Asia, forcing air to flow in the southerly direction over the Himalayas. But in Central Asia as there is no substantial source for water to be diffused as vapour, the winter winds blowing across South Asia are dry. In the summer months the Central Asian plateau heats up more than the ocean waters to its south. As a result, the air above it rises higher and higher, creating a zone of low pressure. Off-shore high-pressure systems in the Indian Ocean push the moist summer air inland toward the low-pressure system. When the moist air meets mountains, it rises and upon subsequent cooling, its moisture condenses and is released as rain, typically heavy rain. The wet summer monsoon winds cause precipitation in India and all along the layered southern slopes of the Himalayas. This forced lifting of air is called the orographic effect.


Winds

The vast size, huge altitude range, and complex topography of the Himalayas mean they experience a wide range of climates, from humid subtropical in the foothills to cold and dry desert conditions on the Tibetan side of the range. For much of the Himalayas—in the areas to the south of the high mountains, the

brings winter precipitation, especially in the west. Heavy rain arrives on the southwest monsoon in June and persists until September. The monsoon can seriously impact transport and cause major landslides. It restricts tourism – the trekking and mountaineering season is limited to either before the monsoon in April/May or after the monsoon in October/November (autumn). In Nepal and Sikkim, there are often considered to be five seasons: summer,

in the east, compared to only during the same period in Shimla in the west. The northern side of the Himalayas, also known as the Tibetan Himalaya, is dry, cold and, generally, windswept particularly in the west where it has a cold desert climate. The vegetation is sparse and stunted and the winters are severely cold. Most of the precipitation in the region is in the form of snow during the late winter and spring months. Local impacts on climate are significant throughout the Himalayas. Temperatures fall by 0.2 to 1.2 °C for every rise in altitude. This gives rise to a variety of climates from a nearly tropical climate in the foothills, to tundra and permanent snow and ice at higher elevations. Local climate is also affected by the topography: The leeward side of the mountains receive less rain while the well exposed slopes get heavy rainfall and the rain shadow of large mountains can be significant, for example leading to near desert conditions in the Upper Mustang which is sheltered from the monsoon rains by the Annapurna and Dhaulagiri massifs and has annual precipitation of around , while Pokhara on the southern side of the massifs has substantial rainfall ( a year). Thus although annual precipitation is generally higher in east than the west, local variations are often more important. The Himalayas have a profound effect on the climate of the

Ecology

The flora and fauna of the Himalayas vary with climate, rainfall, altitude, and soils. The climate ranges from tropical at the base of the mountains to permanent ice and snow at the highest elevations. The amount of yearly rainfall increases from west to east along the southern front of the range. This diversity of altitude, rainfall, and soil conditions combined with the very high snow line supports a variety of distinct plant and animal communities. The extremes of high altitude (low atmospheric pressure) combined with extreme cold favor

, king of all mountains and the father of the goddess Parvati. The Himalayas are also considered to be the father of Ganga (the personification of river Ganges). Two of the most sacred places of pilgrimage for the Hindus are the temple complex in Pashupatinath and Muktinath, also known as Saligrama because of the presence of the sacred black rocks called saligrams. The Buddhists also lay a great deal of importance on the Himalayas. Paro Taktsang is the holy place where

started in Bhutan. The Muktinath is also a place of pilgrimage for the Tibetan Buddhists. They believe that the trees in the poplar grove came from the walking sticks of eighty-four ancient Indian Buddhist magicians or ''mahasiddhas''. They consider the saligrams to be representatives of the Tibetan serpent deity known as Gawo Jagpa. The Himalayan people's diversity shows in many different ways. It shows through their architecture, their languages, and dialects, their beliefs and rituals, as well as their clothing. The shapes and materials of the people's homes reflect their practical needs and beliefs. Another example of the diversity amongst the Himalayan peoples is that handwoven textiles display colors and patterns unique to their ethnic backgrounds. Finally, some people place great importance on jewelry. The Rai and Limbu women wear big gold earrings and nose rings to show their wealth through their jewelry. Several places in the Himalayas are of religious significance in

Resources

The Himalayas are home to a diversity of medicinal resources. Plants from the forests have been used for millennia to treat conditions ranging from simple coughs to snake bites. Different parts of the plants – root, flower, stem, leaves, and bark – are used as remedies for different ailments. For example, a bark extract from an '' Abies pindrow'' tree is used to treat coughs and bronchitis. Leaf and stem paste from an '' Andrachne cordifolia'' is used for wounds and as an antidote for snake bites. The bark of a '' Callicarpa arborea'' is used for skin ailments. Nearly a fifth of the gymnosperms, angiosperms and pteridophytes in the Himalayas are found to have medicinal properties, and more are likely to be discovered. Most of the population in some Asian and African countries depends on medicinal plants rather than prescriptions and such. Since so many people use medicinal plants as their only source of healing in the Himalayas, the plants are an important source of income. This contributes to economic and modern industrial development both inside and outside the region. The only problem is that locals are rapidly clearing the forests on the Himalayas for wood, often illegally.
