The La Nina phenomenon is developing slowly.. What is the relationship between this and the development of the Siberian High and the formation of cold waves in some Arab countries?
Arab Weather - The latest outputs of numerical models indicate the continuation of neutral conditions in the tropical Pacific Ocean, and meteorologists say that indicators support the development of the La Niña phenomenon later this year, with a 60% probability of its occurrence in the period from September to November.
Weather forecasters at Arab Weather said that recent weather conditions in the tropical Pacific Ocean indicate that the temperature difference from the average in the El Niño 3.4 region is -0.3 degrees Celsius, which is the same as the average temperatures for last September, giving us a view of the high probability of the development of a weak La Niña phenomenon later this year.
La Niña is the cold phase of the Pacific Ocean Oscillation, when the waters of the tropical region begin to drop significantly below their general rates. La Niña is linked, without certainty, to the formation of extreme cases during the winter season in several parts of the world, especially Europe and America, in addition to its link to the decrease in wind shear in areas favorable for the formation of tropical cyclones in the Pacific and Atlantic Oceans, which increases the possibility of the development of tropical cyclones significantly.
According to the average sea surface temperatures in the Pacific compared from July 1 to September 29, 2024, it is noted that the warmer than average areas in the main El Niño region in the tropical Pacific are starting to be replaced by cooler than average waters, a sign that the La Niña phenomenon is already developing, but despite this, it is likely to be weak, with a maximum of between -0.9 and -0.5 degrees Celsius.
La Niña phenomenon is statistically linked to the development of the Siberian High
Weather forecasters said that the development of the La Nina phenomenon is statistically linked to the development of the Siberian high in the middle of the Asian continent, which increases the possibility of waves of cold and frost extending to the Arab countries located near it, including the countries of the Levant and the Arabian Peninsula, later this winter.
