در ایام مذکور بخش موثر دریای سرخ بر بارش کشور بسیار فعال بنظر میاد .
بهزاد جان سلام
گستره هوای سرد و عمق نفوذ ناوه در تراز 500 در روزهای سه شنبه و چهارشنبه هفته آینده بسیار مطلوب بنظر میرسه و اینکه آیا کانتر 528 نفوذ میکنه یا نه هنوز زوده برای اظهار نظر.
در واقع باید بگیم که کشور ما از منطقه پشته پرفشار سیبری خارج میشه و این پشت با حرکت چشمگیر به سمت شرق موثر بر شبه قاره هند میشه و همزمان بخش بزرگی از اروپا هم یعنی نیمه غربیش بصورت مورب از جنوب به شمال شاهد فرارفت هوای گرم افریقایی خواهد شد. بخش شرقی اروپا و بالکان که امسال زمستان گرم و بدون برفی داشته هم روزهای سرد و پر برفی رو تجربه خواهند کرد.
خرسهاي قطبي كه دست به كار شدند!
درود
تبریک به بچه های شمال شرق:گل:
به کمینه صبح شنبه دقت کنید چ خبره! اواخر اردیبهشت!!!
