GA Notes

Atmospheric Circulation

The movement of air in the air is known as atmospheric circulation.

Earth’s atmospheric circulation is an important transfer mechanism for both energy and mass.

The atmospheric circulation, speed and direction of winds are controlled by several forces.

These forces are as follows-

1. Gravitational Force of the Earth

2. The Pressure Gradient Force

3. The Coriolis force

4. The Friction Force

Gravitational Force of the Earth:

The gravitational force of the Earth is equally compressing the atmosphere near the ground world-wide.

Density of air pressure decreases as altitude increases.

The Pressure Gradient Force:

This force drives air from areas of higher pressure to areas of lower pressure that causes wind.

The Coriolis force:

It is a type of deflective force which appears to deflect wind from a straight path in relation to Earth’s rotating surface.

It deflects winds to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.

The Friction Force:

This force drags on the wind as it moves across surfaces.

It decreases with height above the surface.

Its effect extends to a height of about 500m.

Effect of friction force varies with surface texture, wind speed, time of day and year, and atmospheric conditions.

वायुमंडलीय परिसंचरण

हवा में हवा की चाल को वायुमंडलीय परिसंचरण के रूप में जाना जाता है।

पृथ्वी का वायुमंडलीय परिसंचरण ऊर्जा और द्रव्यमान दोनों के लिए एक महत्वपूर्ण स्थानांतरण तंत्र है।

वायुमंडलीय परिसंचरण, गति और हवाओं की दिशा को कई बलों द्वारा नियंत्रित किया जाता है। 

ये बल इस प्रकार हैं-

1. पृथ्वी का गुरुत्वाकर्षण बल

2. दबाव ग्रेडिएंट फोर्स

3. कोरिओलिस बल

4. घर्षण बल

पृथ्वी का गुरुत्वाकर्षण बल:

• पृथ्वी का गुरुत्वाकर्षण बल समान रूप से जमीनी स्तर के निकट वायुमंडल को संकुचित कर रहा है।
• ऊंचाई बढ़ने के साथ वायुदाब का घनत्व कम हो जाता है।

दबाव ग्रेडिएंट फोर्स:

• यह बल उच्च दबाव के क्षेत्रों से निचले दबाव के क्षेत्रों में हवा चलाता है जो हवा का कारण बनता है।

कोरिओलिस बल:

• यह एक प्रकार का रक्षात्मक बल है जो पृथ्वी की घूर्णन सतह के संबंध में एक सीधी राह से हवा को विक्षेपित करता हुआ दिखाई देता है।
• यह उत्तरी गोलार्ध में दाईं ओर और दक्षिणी गोलार्ध में बाईं ओर हवाओं को रोकती है।

घर्षण बल:

• यह बल हवा में घूमता है जैसे कि यह सतहों के पार जाता है।
• यह सतह से ऊपर की ऊंचाई के साथ घट जाती है।
• इसका प्रभाव लगभग 500 मीटर की ऊंचाई तक फैला हुआ है।
• घर्षण बल का प्रभाव सतह की बनावट, हवा की गति, दिन और वर्ष के समय और वायुमंडलीय स्थितियों के साथ बदलता रहता है।
