بهش بی محلی کن دیگه چیزی نمیگه.یعنی این مدل جی اف اس واقعا رو اعصابه ها....
فقط الآن نیروی دریایی و ECMWF باید بهش توجه کرد.....

هادی جان میشه اپدیت برف نیرو دریایی رو واسع هفته بعد بزاری؟!
هادی جان میشه اپدیت برف نیرو دریایی رو واسع هفته بعد بزاری؟!
ممنون میشم.
اوکی داداش ممنون.
پيش بيني بارش برف نداره
یکم سختگیر شده امسال مدل نیرو دریاایی نمیدونم واسه چی..هادی جان میشه اپدیت برف نیرو دریایی رو واسع هفته بعد بزاری؟!
ممنون میشم.
طوفان های زمستانی فرا گرمسیری هستند که ازترکیب هوا سرد گرم تشکیل میشن...بادهای شدیدی که اسیب و خسارت میزنه به نواحی ساحلی اقیانوس ها هاریکن نیستند بلکه سیلیکون های گرمسیریند.جمع اوری اطلاعاتی که محدود میشه به سرزمین های فراگرمسیری در این زمان برای این است که از محافظت ضعیف و نمونه های حداقل در این مورد جلوگیری بشه...در مناطق دیگری از ایالات جنوبی سیل پدیده ای است که بیشتر در زمستان و بهار رخ میده... طوفان هایی که در نقاط دیگه رخ میده سیلیکو نهای فراگرمسیری هستند...وسعمون همین قدر بود امیر جانآماده سازی اذهان عمومی!!!!
Winter storms are extratropical storms and all are a mixture of warm and cold air.لطفا در مورد عبارات بالا و اونچیزیکه ازش برداشت میکنید اظهار نظر کنید !
The strong winds that hit the Pacific Coast are from extratropical storms, not hurricanes, which are tropical cyclones.
Data collection was limited to extratropical regions to avoid the poor preservation and minimal sampling associated with tropical environments during this time .
Elsewhere in the southern states, flooding is mostly a winter-spring phenomenon, associated with unusually frequent or active extratropical depressions and fronts.
Storms that form elsewhere are extratropical cyclones.
ترس و دلهره نداشته باشید و هر چیزیکه به ذهنتون میرسه رو بیان کنید لطفا.
استاد من اون یکی اولی رو بزور ترجمه کردم یعنی هنوز مونده ترجمه اش تموم بشه•Tropical cyclones transform into extratropical cyclones as they move northward, usually between 30° and 40° latitude. •Interaction with upper-level troughs or shortwaves in the westeries, and preexisting baroclinic zones is an important factor in ET. •During extratropical transition, cyclones begin to tilt back into the colder airmass with height, and the cyclone's primary energy source converts from the release of latent heat from condensation (from convection near the center) to baroclinic processes. •The low pressure system eventually loses its warm core and becomes a cold-core system. During this process, a cyclone in extratropical transition will invariably form or connect with nearby fronts and/or troughs. Due to this, the size of the system will usually appear to increase. After or during transition, the storm may re-strengthen, deriving energy from primarily baroclinic processes, aided by the release of latent heat. The cyclone will also distort in shape, becoming less symmetric with time, but sometimes retains a tight, tropical-like core.
Extratropical Transition
•A significant number of tropical cyclones move into the midlatitudes and transform into extratropical cyclones.
•This process is generally referred to as extratropical transition (ET).
•During ET a cyclone frequently acquires increased forward motion and sometimes intensify substantially, so that such systems pose a serious threat to land and maritime activities.
•Often poorly forecast by current day numerical models and associated with periods of poor synoptic predictability over a wide area downstream.
•Extratropical transition occurs in nearly every ocean basin that experiences tropical cyclones with the number of ET events following a distribution in time similar to that of the total number of tropical cyclone occurrences.
•The largest number of ET events occur in the western North Pacific while the North Atlantic basin contains the largest percentage of tropical cyclones that undergo ET with 45% of all tropical cyclones undergoing ET.
•Tropical cyclones transform into extratropical cyclones as they move northward, usually between 30° and 40° latitude.
•Interaction with upper-level troughs or shortwaves in the westeries, and preexisting baroclinic zones is an important factor in ET.
