June 2021 release .
The issuance of these forecasts depends on studying the behavior of temperature and atmospheric pressure in the northern hemisphere, including the atmosphere and major water bodies, and integrating those forecasts with global monitoring centers, to come up with the highest possible forecast.
Arab weather experts in the Scientific Research and Development Department have developed scientific methods that are considered the first of their kind in the Arab world and the world, relying on artificial intelligence in forecasts for the coming months, by developing complex mathematical algorithms and equations to detect atmospheric behavior and correct long-range weather forecasts.
In contrast to the daily weather forecast, these bulletins focus on listing the general weather during a month, as the aim is to know the deviation of rainfall amounts and temperatures from their general rates. Many meteorologists in the world are busy trying to decipher the mystery of making accurate seasonal forecasts by conducting many researches in this regard, in which the Arab Weather team participates in part.
The desired benefit of the quarterly bulletins lies in assisting the various sectors in the early planning for the fall and winter alike, especially the agricultural sector, which builds its agricultural plans on these indicators that sometimes help to reap and achieve profits by exploiting this information, in addition to many other sectors that Benefit from these forecasts, such as the commercial sectors, the apparel sector, the energy sector and others.
Seasonal rains are less than normal in southern Saudi Arabia.
Hotter weather in different parts, especially in the east and center of the Kingdom.
Indications of the increased activity of the monsoon winds during the second half of the month.
Gradual increase in humidity in the eastern coasts and the Red Sea.

Description of the week
The tropical high is expected to extend towards the northeast of the Arabian Peninsula in conjunction with the rush of an extension of a moderately temperature air mass from the north of the region and the Levant, which means the rush of warm and humid currents towards parts of southern Arabia and Saudi Arabia at intervals and scattered thunder showers, especially in southern Saudi Arabia, Yemen and parts of The Sultanate of Oman, however, remains below its normal rates, and the surface winds activate the areas of northeastern Saudi Arabia and parts of Iraq and Kuwait, causing some dust and dust in some areas.

Description of the week
The dominance of the tropical high continues towards parts of central and western Saudi Arabia, with less cold air basins continuing to rush towards the northwest of the Arabian Peninsula and across the Levant and Egypt. Some warm and humid southern currents rush from the Arabian Sea and the southern Red Sea, which means that thunder clouds continue to form in parts of the southern island. Arabia, Saudi Arabia and Yemen. It is expected that temperatures will be significantly higher than their average rates in western Saudi Arabia and western Arabia in general.

Description of the week
The dominance of the tropical high is increasing in the central and northeastern parts of the eastern Arabian Gulf in conjunction with the rush of moderately warm air masses from the center of the European continent to parts of the Maghreb, and this means that the values of atmospheric pressure on the east of the Arabian Peninsula in particular become higher than the general rates, while the chances of The rains are, however, less than their normal rates in southern Saudi Arabia, Yemen and the outskirts of the Sultanate of Oman. It is also expected that the Al-Bawareh monsoon winds will gradually start activity on eastern and parts of central Arabia.

Description of the week
The subtropical air altitude is intensifying, especially over Iran and eastern Arabia, with cold air depressions rushing towards the north and center of the European continent, an extension of the central Mediterranean, that may work on the activity of the Red Sea depression weakly, and this leads to the weather being hotter than usual in most areas, with the survival of Rain opportunities are present, especially in southwestern Saudi Arabia and Yemen. It is also expected that the activity of the Al-Bawareh winds will increase, to include large parts of eastern and central Saudi Arabia and the eastern Gulf states.
Arctic and North Atlantic
The Arctic Oscillation Index (AO) is expected to behave in a neutral to light positive pattern during the first half of the month at least, and this is considered a normal behavior for this time of the year.
As for the North Atlantic Oscillation coefficient (NAO), it is expected to start similar to the Arctic coefficient, provided that it continues its behavior during most periods of the month within its normal range.
These conditions are often associated with a good distribution of moderately hot air masses in the Levant and northern Arabia in most periods of the month, while hotter air masses dominate parts of western Europe and parts of northern Maghreb during exciting periods of the month.
Tropical Pacific Ocean
The equatorial Pacific is still under the influence of the neutral phase, as the report of the National Oceanic and Atmospheric Administration (NOAA) showed expectations for the continuation of the neutral phase during the summer of 2021, with a high probability of about 67%.
The rise in the ENSO index is linked to a statistically significant improvement in the chances of rain in the Arabian Peninsula and the Horn of Africa.
It also indirectly affects the movement of jet streams in the upper climatic layer of the atmosphere.
Indian Ocean and Arabian Sea
The IOD index exhibits neutral values and is expected to decline to negative values during the next two months, as the chances of tropical weather conditions will decrease in the Indian Ocean and the Arabian Sea during the current summer, and it also affects more strongly the weak chances of rain in the Arabian Peninsula and the Horn of Africa, where the decrease in chances of rain is evident. Rain and torrential rain during the current period, especially during the forecasts of global models.
