Since 1985 there has been rapid and permanent change in the rainfall patterns of Arabia, barely noticed or reported outside of the areas that have been impacted by the increased rainfall and floods, and seemingly overlooked by most climatologists and meteorologists.
Several thousand years ago, prior to the time before humans domesticated grazing animals like camel, sheep, goats and cattle, the area from western India, Pakistan and Arabia was covered with a savanna-grassland with rivers, lakes, freshwater marshes and waterfalls.
When the perennial native grass and wildflower cover and savanna trees of the area were removed by the domestication of grazing animals and the area changed to desert.
When people started protecting flocks of grazing animals from natural predators, and eventually drove the predators to extinction, then grazing animals who eat the native grasses were able to multiply beyond what the grassland ecosystem could reasonably sustain.
When the grasslands were destroyed, the vegetation cover was no longer there to cool the soil surface, so that clouds were no longer able to form and rain on those lands during the summer monsoons. Within a short amount of time, perhaps only a few human generations, the climate went from savanna-grasslands to barren desert.
When the perennial native grass and wildflower cover was grazed away, it exposed the bare soil, and that soil started getting airborne, which produced a Dust Cloud hovering over Pakistan and Arabia each year.
A similar Dust Cloud event happened in the United States from Texas to Colorado in the 1930s, and it was called the "Dust Bowl", which lasted only a decade, because those areas were replanted with vegetation in the 1940s. If in the USA, the 'Dust Bowl" millions of acres had not been replanted, those Dust Cloud conditions could have been made a permanent part of North America, just like the Dust Cloud has existed for thousands of years in Pakistan to Arabia.
The "Dust Bowl" conditions from Pakistan to Arabia, have lasted for about 5,500 years. While the dust cloud strength has been about the same for thousands of years, a change occurred in 1985 when global warming strengthened the atmospheric moisture and has been able to break through the Dust Cloud wall.
The normal rainfall pattern for Arabia was described in the book "Unknown Oman" by Wendell Phillips (1966):
For centuries, with the exception of Salalah in Oman, the annual rainfall of Arabia has been consistently low each year, as described by Phillips (page 217), "Two or three hours of heavy rain a year means a good year whereas farther north in the dunes thirty to forty minutes of rain in one solid shower will moisten the sands sufficiently to produce adequate grazing for a period of twelve months."
Phillips writes that the exception in Arabia, is the area around Salalah in Oman, (page 168-9) "the narrow half-moon shaped coastal plain of Dhofar is an abnormal feature in this otherwise arid South Arabian coast the monsoon from which Dhofar derives its unique climate, with its inflow of fog and drizzle summer rain yields five inches on the coast and fifteen inches in the mountain.
"The Qara Mountains rise steeply to the north, limiting the coastal plain to a maximum width of ten miles. Within these mountains lovely secluded little lakes and gorges rich with tropical ferns and running streams. Sycamore, myrtle, white jasmine, and acacia trees abound."
Phillips also writes about unusual torrential rainfall events (page 164) only hitting Arabia twice in 600 years prior to 1890, the cyclonic storms of 1286, and 1325. Then on June 4, 1890, twelve inches of rain fell in 24 hours throughout Oman, killing 700 people and uprooting over 100,000 date palms. When Phillips was in Oman in late January 1958, heavy rains caused great damage across the county.
So from 1200 and 1889, two torrential rainfall events occurred in Arabia, then from 1890 to 1958, there were two more events.
Currently torrential rainfall evens in the Arabian peninsula are occurring annually to several times a year.
For five thousand years, the Pakistan-Arabia Dust Cloud was able to kill the rain clouds before they formed over Arabia during the monsoon season, but the increase in monsoonal moisture due to global warming is overwhelming the Dust Cloud.
Additionally, an ancient moisture pattern in spring March to June is beginning again after a several thousand year absence, originating from South America through central Africa, and then moving north to the west coast of Arabia. This pattern coupled with the East Indian monsoon moisture, may have been the cause of the Biblical flood story, occurring in Arabia from April to June for 40 days and 40 nights, many thousands of years ago.
And on June 2, 2012, the air temp. of the Holy city of Mekkah reached a new record of 124.5°F, and two days later rain fell when the air temperature was 109°F. (43°C), so the summer rainfall is returning to Arabia, despite the Dust Cloud and despite the heat, and the rain that fell on June 4th was about 100° F. by the time reached the ground.

May 9 = Israel had "Biblical rains" flooding the desert near Dead Sea, also in Sinai, Egypt flooding at http://www.jpost.com/National-News/Late-spring-rain-brings-Israel-to-a-halt-351631
Dr. Baruch Ziv, a climate scientist at the Open University, told the Post. Lightning frequency was very high, a typical component of tropical storms, and the intensity of the rains were extreme, Ziv added.
The strong storms carried with them widespread thunder and lightning and drenched the country with rain almost nonstop from Wednesday night through Thursday morning, IMS data, provided by Porat, said. Up until Thursday afternoon, the largest amount of rains fell in the Shfela region, with about 50-80 mm. accumulating there. In most monitoring stations stretching from the North to the northern Negev, between 20-50 mm. piled up, the data said.
The station at Tzora, in the Mateh Yehuda Regional Council, received 82 mm. of rain, the maximum amount of rain accumulated in a single May day in Israel since 1963, when 93 mm. fell in Afula, according to IMS.
"This event was exceptional or even unique for May," Ziv said. "I think that there was not even one rain station in Israel that didn't get rain."

Google Earth image from 50 miles NE of Riyadh, showing an example of the area north and south of Riyadh that was within historic times, a lush grassland and open forest fed by hundreds of streams and rivers that flowed year-round, and were from 1-3 meters to about 10 meters deep.
The summer temperatures currently have daytime highs of 115 deg. f. and 90 deg. F. nights, and if the native grasslands and other native vegetation were back covered the land, the temperatures would probably be between 80 and 90 degrees F. all through summer, more like Salalah, Oman is today.
