MONSOON DESK

South Asian Monsoon

India’s climate is dominated by monsoons. Monsoons are strong,often violent winds that change direction with the season. Monsoon winds blow fromcold to warm regions because cold air takes up more space than warm air. Monsoonsblow from the land toward the sea in winter, and from the sea toward land inthe summer.

India’s winters are hot and dry. The monsoon winds blow from thenortheast and carry little moisture. The temperature is high because theHimalayas form a barrier that prevents cold air from passing onto thesubcontinent. Additionally, most of India lies between the Tropic of Cancer andthe equator, so the sun’s rays shine directly on the land. The temperature canreach as high as 110oF during the Indian winter.

The summer monsoons roar onto the subcontinent from thesouthwest. The winds carry moisture from the Indian Ocean and bring heavy rainsfrom June to September. The torrential rainstorms often cause violentlandslides. Entire villages have been swept away during monsoon rains. Despitethe potential for destruction, the summer monsoons are welcomed in India.Farmers depend on the rains to irrigate their land. Additionally, a great dealof India’s electricity is generated by water power provided by the monsoonrains.

Pakistan is much drier than India. The summer monsoon winds inIndia bring moisture from the Indian Ocean; Pakistan is north of the ocean andreceives much less rain. The Thar Desert is on the border between India andPakistan. It covers more than 77,000 square miles, about the size of Nebraska.

 

Dominant control of the South Asian monsoon byorographic insulation versus plateau heating

The Tibetan plateau, like any landmass, emits energy into the atmosphere in the form of dry heat and water vapour, but its mean surface elevation is more than 5km above sea level. This elevation is widely held to cause the plateau to serve as a heat source that drives the South Asian summer monsoon, potentially coupling uplift of the plateau to climate changes on geologic timescales1–5.

East Asian monsoon climate during the Late Pleistocene:

high-resolution sediment records from the South China Sea

Based on the study of 10 sediment cores and 40 core-top samples from the South China Sea (SCS) we obtained proxy records of past changes in East Asian monsoon climate on millennial to bidecadal time scales over the last 220,000 years. Climate proxies such as global sea level, estimates of paleotemperature, salinity, and nutrients in surface water, ventilation of deep water, paleowind strength, freshwater lids, fluvial and=or eolian sediment supply, and sediment winnowing on the sea floor were derived from planktonic and benthic stable-isotope records, the distribution of siliciclastic grain sizes, planktonic foraminifera species, and the UK 37 biomarker index.

Monsoon flash floods inundate ailing economy

Aug 28, 2013

KARACHI – Flash floods caused by the recent monsoon rains and melting of summer ice has reportedly affected 1.4 million lives.

Though the flood was categorised as medium-high level, the momentum is phasing out. As per rough estimates made by National Disaster Management Authority the losses to the agriculture sector is estimated at Rs 200 billion due to damages to 1.05m acres of standing crop. "Historical trend reveals that agricultural loss due to floods makes about 50 percent of total loss to the economy," said Zeeshan Afzal, an analyst at Top line Research. He said the Met Office had predicted above average rains during September which carries a potential to augment losses and worsen the situation.

Pounds of Prevention - Disaster Risk Reduction Story - Focus: South Asian Monsoon Prevention

Monsoons are seasonal shifts of prevailing winds that bring rainfall, typically during the months of June through September in South Asia. Monsoon rains are both a regular and vital part of life and a potential source of catastrophic floods. Variability in their characteristics—such as when monsoon rains start and end, total rainfall amount, and rainfall intensity—may have a dramatic impact on people and their livelihoods. In recent years, Bangladesh, India, Nepal, Pakistan, and Sri Lanka have experienced the effects of flooding, including damage to homes, livelihoods, and crops.
