Difference between season and weather in Hindi

  Season vs weather in Hindi  मौसम और मौसम ऋतु दोनों हमारे प्राकृतिक वातावरण से संबंधित होते हैं। हालांकि, दोनों में अंतर होता है। मौसम वर्षा, गर्मी, सर्दी और शीतलावकाश जैसी विभिन्न अवधियों में बदलता है, जबकि मौसम ऋतु बरसात, ग्रीष्म, वर्षा और शीतकाल जैसी विभिन्न ऋतुओं में बदलता है। मौसम एक संक्षिप्त अवधि में होने वाले मौसम परिवर्तनों को दर्शाता है। यह अतिरिक्त वर्षा, बारिश, तूफान, बर्फबारी, अधिक गर्मी या ठंड, बादल आदि के रूप में प्रभावित हो सकता है। मौसम अत्यधिक अनिश्चित होता है। इसलिए, हम सामान्य रूप से दैनिक मौसम पूर्वानुमान का उपयोग करते हैं ताकि हम सही तरीके से अपनी वेशभूषा चुन सकें। दूसरी ओर, मौसम ऋतु एक लंबी अवधि होती है जो वर्षा, ग्रीष्म, वर्षा और शीतकाल के रूप में बदलती है। यह एक समय-सीमा रूपी स्थिरता होती है जो अपने आप में ही एक बड़ा विभाजन लाती है।
