Smog From Agricultural Fires in Thailand

Myanmar and Thailand – March 25th, 2013

Every year between February and April local farmers in Northern Thailand and neighboring countries burn huge amounts of vegetation to clear fields and get rid of agricultural waste. The result is a serious, regional smog problem that causes discomfort and health issues for millions of people. Here, the haze covers much of Thailand and spreads towards neighboring countries such as Myanmar (left).

Sediments, Haze and Various Cloud Phenomena Near Yangtze River Mouth, China

China – March 21st, 2013

The Yangtze River empties a thick load of sediments into the waters of the Yellow Sea, tinging them gold and making apparent the reason for the sea’s name. To the northwest, haze hangs over the plain near Beijing and over the Bohai Sea. East of the rivermouth, two other kinds of atmospheric phenomena can be observed: wave clouds (the straight, parallel lines of clouds) and van Kármán vortex streets (the clouds organized into two rows of spirals).

Haze Over Yangtze River Mouth, China

China – March 10th, 2013

Haze that is likely a combination of smog and dust from a dust storm spreading across China hovers over the mouth of the Yangtze River and blows eastward, south of the Korean Peninsula, towards Japan. Partially visible through the haze are sediments from the Yangtze. Sediments and phytoplankton growth also color the waters of the Bohai Sea and Yellow Sea.

Smoky Haze Over Myanmar – March 17th, 2013

Myanmar – March 10th, 2013

A thick haze hangs over Myanmar (right) and spreads into neighboring countries, including India’s far northeast. The haze is basically an annual event, usually caused by large fires in Myanmar and other countries in Southeast Asia.

Such fires, which are typically set by farmers for clearing rice stubble to make room for new crops, grow out of control, and are largely ignored. Many spread into national parks to mingle with existing fires deliberately set to control undergrowth.

Although slash-and-burn agriculture and the deliberate setting of fires are illegal, measures are rarely taken to stop farmers from setting fires around this time every year. Even when the fires themselves don’t pose much of a threat, the accumulated smoke particles do raise concerns. In the past, the particulate count has reached more than six times higher than what is generally considered safe (click here for more information).

Dust and Haze Over Northeastern China

China – March 10th, 2013

A cloud of dust that has swept across northeastern China from near the border with Mongolia can be seen stretching towards Beijing and the Bohai Sea (upper right). The dust intermingles with haze, in the lower half of the image, reaching the coast by Shanghai (right). The haze may be a combination of smog, dust and other forms of air pollution.
