The climate of Rubhari Desert

The desert spans 22 latitudes from the north latitude 12-34 line; Although most of the desert is north of the Tropic of Cancer, it is still regarded as a tropical desert. It is extremely hot in summer, with the temperature as high as 54℃( 129℉) in some places. Dry and hot inland, tolerable. However, coastal areas and some highlands are restricted by high humidity in summer, and there is dew or fog at night or early morning. The average annual rainfall in the whole desert is less than 100 mm (4 inches), but the rainfall range is 0-500 mm (0-20 inches). Except for intermittent rainfall in winter, smog or sandstorm in spring, the inland sky is usually clear. Rainstorms occasionally flood major river basins. It is cool in winter, and the coldest weather appears at high altitude and in the northernmost part. In 1950, the lowest temperature recorded in Tulef near the taplin oil pipeline (trans-Arabian oil pipeline) was-12℃, several inches of snow fell, and the pond was frozen 1 inch. The summer rainfall in the Rubhari Desert comes from the Indian Ocean monsoon. There may be winter rain in the Lubri Desert in the north. The driest part of the Arabian desert seems to be on the western edge of the Rubhari desert, north of Wadi Adeba Sil.

The wind mainly blows from the Mediterranean, and then blows to the east, southeast, south and southwest, drawing a huge arc. The windy season occurs from 12 to 1 and May-June of the following year. This period is called hot dust wind, which lasts for 30-50 days and the average wind speed is 48 kilometers per hour. Hot dust wind, which can test the patience of people trapped in the wind, is a dry wind that carries a lot of dust and changes the shape of sand dunes. Every storm brings millions of tons of sand into the Lubuhari Desert. The blown sand is only a few feet above the ground, unless it is picked up by cyclones, dust rolls or regional sandstorms. In the middle of Inner Mongolia and the southwest of Lubuhari Desert, winds are blowing from all directions in turn. Strong southeast wind swept across the desert for several days at a time, reversing the influence of hot dust wind on sand dune formation.
