در درون دریاها، رودخانه های واقعی در جریان هستند که بخاطر گوناگونی حرارت و مقدار نمکشان، آنها را جریان های آب سرد و گرم نامیده اند.گلف استریم ،یک جریان اقیانوسی گرم و قوی است که مانند رودخانه عظیم و مرموزی در اقبانوس نیلگون اطلس جاری است و یکی از عظیم ترین و نیرومند ترین جرانهای آب دنیا محسوب می شود . این جریان جالب در هرساعت قریب یک صد میلیارد متر مکعب را با سرعتی بهت آور در میان تنگه های کرانه فلوریدا( Florida ) درخلیج مکزیک سرازیر می کند و رودخانه های عظیمی مثل آمازون ویا نیل در برابر عظمت این جریان آب گرم به منزله رودهای کوچکی هستند .


(جریان گلف استریم به رنگ زرد دراقیانوس آتلانتیک)
گلف استریم حدود ۱۰۰ کیلومتر عرض و ۸۰۰ تا ۱،۲۰۰ متر عمق دارد و سرعت آب در سطح آن ۲.۵ متر در ثانیه استو حرارتی که توسط آن انتقال می یابد برابر با ۱.۴  پتا وات (۱۵ ۱۰ وات) که برابر است با صد برابر انرژی مصرفی جهان می‌باشد.

جریان آب‌های گلف استریم رنگ مشخصی دارد. رنگ گلف استریم آبی نیلی روشن است بنابراین جریانش در میان آب‌های سبز و خاکستری رنگ اطراف خود، به خوبی نمایان است. آب گلف استریم از حرکت آب‌های سطحی نزدیک استوا، در اقیانوس اطلس، جریان می‌یابد، و این «جریان» به سوی غرب به پیش می‌رود. طول آن ۱۲۰۰۰ مایل می‌باشد و مسافرت آن برای طی این مسیر حدود سه سال می‌باشد. که برای اثبات این ادعا دانشمندان تعدادی از بطری‌های محتوی نامه به زبان‌های متفاوت را در مسیر جریان گلف استریم قرار دادند و این بطری‌ها بعد از ۳ سال به نقطه ابتدایی رسیدند.

فایده وجود این جریان:

وجود چنین جریان بزرگی از آب گرم سبب دگرگونی‌های چشمگیری در آب و هوای بسیاری از مناطق جهان شده است و به دلیل وجود گلف استریم، لندن و پاریس نیز دارای آب و هوای ملایم زمستانی گردیده‌اند وگرنه این دو شهر های شمال شرق کانادا، در شمال قرار دارند و باید مانند آن زمستانی بسیار طلانی و سرد داشته باشند. حرارت جریان آب گرم گلف استریم مساوی حرارتی است که از سوزاندن دو میلیون تن ذغال بدست می‌آید. شدت و قدرت حرارت این جریان به حدی است که قادر است هوای تمام کشورهای اروپا را گرم کند. اگر فرضاً مقدار ۱۵ درجه از حرارت این رودخانه کاسته شود احتمالاً تمام کشورهای شمالی اروپا مخصوصا انگلستان دچار یخبندان می‌گردد.

 فایده دیگری که این جریان دارد در دنیای کشتیرانی است که درفرن 16 میلادی کشف شد به طوری که اگر کشتیها از روی این جریان گرم از آمریکا وسواحل فلوریدا به سوی اروپا حرکت کنند دو هفته زودتر به مقصد خواهند رسید .

اثر گرم شدن هوا برجریان گلف استریم:

گرم شدن تدریجی آبهای اقیانوسها بعلت پدیده گرم شدن هوا به خاطر پدیده گلخانه ای باعث ذوب شدن یخهای  قطب جنوب شده که بر روی جریان گلف استریم در اقیانوس اطلس تاثیر گذاشته و آنرا نابود می‌کند. امروزه ثابت شده که جریان گلف‌استریم یکی از عوامل اصلی تعادل جوی در کره زمین است. اما خود این جریان به شدت ناپایدار است بطوریکه تغییرات شدید درجه حرارت آب اقیانوس براحتی باعث اختلال در آن می‌شود. بسیاری از دانشمندان وقوع عصرهای مختلف یخبندان در گذشته را به برهم خوردن تعادل جریان گلف‌استریم نسبت می‌دهند

"We have to build to an alternative crescendo, cheri," he said.
"And then we should have an ending which is to be as none before."

His smile was decadent, his eyes were filled with lust, along with the soft skin of his hard cock
against my sex was having its intended effect. I had been feeling a stronger arousal now as I
felt his cock slide between my sensitive lips. I felt the of his cock
push agonizingly at the entrance of my pussy, and I want to him to thrust into me hard.
Instead he retracted and slid his hardness back about my clit.


I'd been aching to have him inside, and I can tell that his need
to push that wonderful hard cock inside me was growing.

His moans grew to suit mine, and I knew the feeling of my wet pussy lips
on the head of his cock was getting an excessive amount of both for of us.


"Permit the finale begin," he stated, and the man slid the end
of his cock inside me.

The two of us gasped as he held his cock there for
the moment. I contracted my pussy to tug him further inside, and then he
threw his return on the sensation. Inch by excruciating
inch he pushed his cock inside me, every time I squeezed
my pussy around him. His cock felt wonderful the way it filled me, but
I needed it all inside me. I rolled sideways and rested my leg against his shoulder, and hubby
plunged his cock up in.

His smile was decadent, his eyes were loaded with lust, and
also the soft skin of his hard cock against my sex was having its intended effect.
I used to be feeling a stronger arousal now as I felt his cock slide between my sensitive lips.
I felt the actual top of his cock push agonizingly at the doorway of my pussy, and I needed him to thrust into me hard.

Instead he pulled back and slid his hardness
back as much as my clit.

I used to be aching to own him inside, and I really could tell
that his should push that wonderful hard cock inside me was growing.
His moans grew to match mine, and I knew the sense of my wet pussy lips for the head of his
cock was getting too much for both of us.

"Permit finale begin," he explained, and hubby slid the top of
his cock inside me.

We both gasped while he held his cock there for your moment.
