Card 1सौर विकिरण

अवरोधन क्या है?

Answer

सौर विकिरण (Insolation) पृथ्वी द्वारा प्राप्त किया जाने वाला सौर विकिरण है। यह वायुमंडल के शीर्ष तक मुख्य रूप से लघु तरंग दैर्घ्य में पहुँचता है। पृथ्वी के वायुमंडल के शीर्ष पर औसतन 1.94 कैलोरी प्रति …

Card 2Solar Radiation

What is insolation?

Answer

Insolation is incoming solar radiation received by the earth. It reaches the top of the atmosphere mainly in short wavelengths. On average, the earth receives 1.94 calories per sq. cm per minute at th…

Answer

The sun’s rays fall more directly near lower latitudes and more slanting at higher latitudes. Slanting rays spread energy over a larger area and pass through a thicker layer of atmosphere, so the ener…

Card 4विकिरण की परिवर्तनशीलता

अक्षांश के साथ आतपन की मात्रा क्यों बदलती है?

Answer

सूर्य की किरणें निम्न अक्षांशों के पास अधिक सीधी पड़ती हैं और उच्च अक्षांशों पर अधिक झुकी हुई पड़ती हैं। झुकी हुई किरणें अधिक क्षेत्र में ऊर्जा फैलाती हैं और वायुमंडल की मोटी परत से गुजरती हैं, इसलिए …

Card 5विकिरण की परिवर्तनशीलता

Answer

मुख्य कारक पृथ्वी का अपनी धुरी पर घूमना, सूर्य की किरणों का झुकाव कोण, दिन की लंबाई, वायुमंडल की पारदर्शिता और भूमि का विन्यास है।…

Card 6Variability of Insolation

What factors cause variation in insolation?

Answer

The main factors are rotation of the earth on its axis, angle of inclination of the sun’s rays, length of day, transparency of the atmosphere, and configuration of land in terms of its aspect.

Card 7Earth-Sun Distance
