The Gobi is 500,000 square miles (1,300,000 square km) and defined as lying between the Altai Mountains and Hangayn Mountains to the north; the western edge of the Da Hinggan Range to the east; the Yin, Qilian, eastern Altun, and Bei mountains to the south; and the eastern Tien Shan to the west.
The Gobi region is in the Himalayan rain shadow, and this desert is one of the world’s most prolific dust-producing regions on Earth. Interesting though, much of the Gobi is not sandy desert but bare rock, and it is possible to drive over this surface by car for long distances in any direction.
These dust storms are not due to mankind’s activities, as they have been occurring for tens of thousands of years. They are the product of waves of dust particles, due to the ‘sparsely vegetated grasslands of the Gobi’, which frequently give rise to dust storms, especially in springtime.
These storms generated in the Gobi Desert of northern China and southern Mongolia are massive volumes of airborne dust particles, occasionally they circumvent the earth. They are swirling low pressure storm systems that kick up dust and sand, often looking pink in color from high altitude.
The beginnings of the Gobi Desert are in Mongolia, blowing the fine airborne particles into China. This has happened thousands of times over eons of times, but in 1970’s-1990’s, it appears that the end results were the beginnings of a wave of allergies to mankind never before experienced before, in-volume. It would appear that the winds in-route, picked up minute particles of many types of molds and combined allergens carnage, and then dispersing them worldwide, thus, it would appear that that was a new addition to mankind’s allergy problems?
As to Global change, it certainly is also a contributor to the increase of allergy problems.
