★ LENTICULAR CLOUDS →

➫ Lenticular Clouds ট্রপোস্ফিয়ারে গঠিত হওয়া এক ধরনের লেন্স (Lens) আকৃতির মেঘ। অনেক সময় ইউএফও (UFO) মেঘও বলা হয়।
➫ ভূপৃষ্ঠের ওপর দিয়ে বায়ু যখন কোনো বিল্ডিং বা পাহাড়, পর্বত দ্বারা বাধা প্রাপ্ত হয়, তখন ঐ বাধাপ্রাপ্ত বায়ু অনেক সময় একই স্থানে পাক খেতে থাকে। এই অবস্থায় বায়ুর অংশবিশেষ উপরের দিকে উঠে গিয়ে শীতল হয়ে ঘনীভূত হয়ে এই ধরনের মেঘ তৈরি করতে পারে।
➫ এই ধরনের মেঘ দেখে অনেক সময় UFO দেখা গেছে বলে ভুল হয় এবং অনেকেই দাবী করে বসে যে তারা UFO দেখেছে।
