السلام عليكم ورحمة الله وبركاته///
نعود لكم  بعد أنقطاع  عدة أشهر، راجياً من الله العلي القدير أن يكون الجميع بأتم صحة وعافية
نبداء هذا الموسم  بإستعراض لبعض التوقعات العالمية والتي في غالبها متشائمة للأسف الشديد
 ولكن أملنا  في الله رب العالمين أكبر من أي شيء  وهو علام الغيوب،
وما هذه التوقعات الا مجرد  مؤشرات  مستخرجة من حواسيب آليه 
 نسبة الخطاء فيها كبير جداً.
كنت خلال الاشهر الماضية أتابع  وبصفة مستمرة جميع التحديثات 
التي تصدر من مراكز الطقس والتي أخرها وللأسف التقرير الصادر يوم أمس
  من المركز الامريكي والاسترالي والذي  يتحدث عن عودة ظاهرة الانينا من جديد
 ولكن حتى الآن لازالت أخف من العام الماضي.
نص التقرير:
 La Niña conditions  have returned and are expected to gradually strengthen and continue into  the Northern Hemisphere winter 2011-12.
La Niña  conditions returned in August 2011 due to the strengthening of negative  sea surface temperature (SST) anomalies across the eastern half of the  equatorial Pacific Ocean (Fig. 1).  With the exception of the far westernmost Niño-4 region, all of the latest weekly Niño index values were –0.5oC or less (Fig. 2).   Also supporting the return of La Niña conditions was the strengthening  of the below-average subsurface oceanic heat content anomaly (average  temperature anomalies in the upper 300m of the ocean, Fig. 3), in response to increased upwelling and further shoaling of the thermocline across the eastern Pacific Ocean (Fig. 4).   The atmospheric circulation over the tropical Pacific continued to  exhibit La Niña characteristics, but remained weaker and less canonical  than the wintertime atmospheric patterns.  For example, convection  continued to be suppressed near the Date Line, but remained south of the  equator, while convection was only weakly enhanced near Papua New  Guinea (Fig. 5).   In addition, anomalous low-level easterly and upper-level westerly  winds persisted over the central tropical Pacific.  Collectively, these  oceanic and atmospheric patterns reflect the return of La Niña  conditions.
     
Over the last  several months many models have predicted increasingly negative SST  anomalies in the Nino-3.4 region during the upcoming Northern Hemisphere  fall and winter. However, the majority of models continue to predict  ENSO-neutral conditions for this period (Fig. 6). The NCEP Climate Forecast System (CFS) has performed quite well over the past several months (Fig. 7)  capturing the recent decrease in SST anomalies.  The better model  performance, combined with the historical tendency for significant La  Niña episodes (as in 2010-11) to be followed by relatively weaker La  Niña episodes, leads to increased confidence that La Niña will persist  into the winter.   While it is not yet clear what the ultimate strength  of this La Niña will be, La Niña conditions have returned and are  expected to gradually strengthen and continue into the Northern  Hemisphere winter 2011-12.
     
Across the  contiguous United States, temperature and precipitation impacts  associated with La Niña are expected to remain weak during the remainder  of the Northern Hemisphere summer and early fall, and to generally  strengthen during the late fall and winter.  During September-November  2011, there is evidence that La Niña favors an increased chance of  above-average temperatures across the mid-section of the country, and an  increased chance of above-average precipitation across the Pacific  Northwest (see 3-month seasonal outlook released on 18 August 2011).
     
This  discussion is a consolidated effort of the National Oceanic and  Atmospheric Administration (NOAA), NOAA's National Weather Service, and  their funded institutions. Oceanic and atmospheric conditions are  updated weekly on the Climate Prediction Center web       site (El Niño/La Niña Current        Conditions and Expert Discussions).  Forecasts for the evolution of El Niño/La Niña are updated monthly in the        Forecast Forum section of CPC's Climate        Diagnostics Bulletin.  The next ENSO Diagnostics Discussion is scheduled for 6 October 2011.  To receive       an e-mail notification when the monthly ENSO Diagnostic Discussions are released, please send an e-mail message       to: ncep.list.enso-update@noaa.gov.

توقعات مبدئية من بعض المراكز العالمية للموسم القادم:
1- المرصد الروسي  ويتوقع أمطار أعلى من المتوسط على الغربية، وأقل من المتوسط على باقي المناطق والله أعلم:
-

2-
وهذا توقع  جميل جداً على الوسطى خلاب شهر أكتوبر (لاحظ اللون الازرق)
 

3-
