The seasonal speed changes ice loss through the high mountainous Asia, and the discovery of the study

Ice rivers throughout the Supreme Mountain Asia lose more than 22 GB of ice annually – equivalent to approximately 9 million Olympic swimming pools, according to a research from the University of Utah and Virginia Tech. The impact of the warming climate on the undisputed ice loss – this new study provides the first evidence that seasonal transformations in rainy patterns and snow, especially the monsoons in South Asia, are also exacerbated by the melting of the ice throughout the region.

“These results highlight that the ice rivers dominated by monsoon winds in South Asia, such as the center of Himalayas, west of Himalayas and East Himalayas, are especially exposed.” Sonam SherbaAssistant Professor at Utah University and the author of the study. “If the timing and intensity of the monsoon winds continues, it may speed up the loss of ice and threaten the availability of water for millions of estuary.”

High Mountain Asia is known as “the third pole” because it carries the largest reserves in the world of ice ice outside the Arctic and the polar pole. Ice rivers in the region feed the lakes and rivers that provide fresh water for more than 1.4 billion people throughout South and Central Asia, maintaining agriculture, hydroelectric energy and drinking water.

“Looking at the future, a faster decline in mountain glaciers will turn the main source of the river flow from the melting of the iceberg to the rain, which increases the risk of dehydration in areas raised for future generations,” he said.

High icy rivers accumulate in the southern parts of the Central Himalayas during the summer, not in the winter. At high altitudes, cold temperatures convert the annual seasonal rains into intense snowfall that nourishes ice rivers. The ice rivers decline because they either receive less snow fall or more melted. While warming itself drives melting, it also changes rain and snow patterns. This can shorten the rainfall season, reduce the amount of precipitation or cause a transformation from the snow to the rain on the ice rivers, which leads to more fusion due to less accumulation on the ice rivers.

Fasting ice melting patterns also carry significant risks. The fusion of fastest fusion can increase the possibility of ice lake floods, an increasing threat in mountainous regions around the world with ice flowers decline in response to climate change. Along with successive successive risks, including landslides and river floods, unstable iceotens can destroy vulnerable societies.

“This risk is not only related to long -term water deficiency, but also about the immediate threats of life and infrastructure,” Sherba said.

Meluvan is driven by seasonal winds: a widespread phenomenon

The authors used satellite data from the task of grace that suffers from NASA sensitive to ice mass losses, along with hydrological and tender records, to assess the effects of warming climate, and changing seasonal rainfalls and advanced monsoon patterns on the melting of the ice escapes and hydrological cycle in the high mountainous Asia.

The main results of the analysis are:

• In the central and western Himalayas areas where ice rivers usually grow during the summer, ice losses are associated with increased precipitation.
• In the eastern regions of the Himalayas, the dynamics of ice can be associated with a decrease in snowfall.
• Repeated patterns of icebergs occur in 3-4.5 years and 5 to 8 years, corresponding to natural contrast in seasonal wind patterns. This raises urgent questions about how the seasonal wind attacks that depend in the future affect the health of the iceberg in the long run.

The researchers emphasize the urgent need for more accurate monitoring networks, more accurate monitoring networks than rainfall, snowfall and relevant climate variables. They argue that improved monitoring systems are crucial to predicting the effects of seasonal wind changes and directive adjustment strategies.
