Floods in Indonesia matched by drought in the Arabian Peninsula .. What is the scientific reason behind this?

Weather of Arabia - Muhammad Awaina - Australia is witnessing floods caused by record rains in several regions in the country, which affects about 10 million of the country's population of about 25 million, and the reason for this is due to the high temperature of the oceans, especially on the surface. Which leads to increased evaporation rates, making the season more humid than usual in those areas.

Record amounts of rain that fell in southeast Australia led to flooding of dams and prompted the authorities to carry out large evacuations, causing the most violent floods in nearly 50 years in some areas, forcing thousands to leave their homes, and damaging hundreds of homes.

Indonesia was not spared from these weather conditions, as at least 157 people were killed and dozens were reported missing in the floods caused by the cyclone "Seroga" in Indonesia and East Timor.

The effect of the phenomenon of lanina

The phenomenon of lanina is known as the temperature drop below levels of 0.5 ° C or more in the eastern equatorial region in the Pacific Ocean, and the phenomenon of lanina is statistically related to fertile seasons in Australia and Indonesia, where it leads to severe disturbances in the movement of the atmosphere, because it controls a large percentage of the movement of subtropical jet currents and some Weather systems such as hurricanes and subtropical highlands, which leads to the formation of floods in several regions, offset by droughts in other areas.

What is the effect of the phenomenon of Lanina on the Arab East?

In contrast, the current winter is one of the driest in parts of the Arabian Gulf and the Sultanate of Oman for several years, as the effect of the lanina phenomenon extends towards the Indian Ocean, as it indirectly leads to a decrease in the surface temperature of the water in the western part of the Indian Ocean and the Sea The Arabs (- IOD ), which acted on the control of the tropical high above the Arabian Peninsula, acted as a buffer against the incursion of the cold upper basins.

In addition to the dry tropical masses that prevailed most of the periods, this means that the humid winds did not push much towards the Arabian Peninsula with specific humidity, depressions and convection.
