If Sinking Air is Warm, Why is it Still High Pressure?

✅ Sinking air always creates High Pressure — Because when air sinks, it compresses and piles up at the surface → meaning more air molecules are pressing down → creating High Pressure , even if the air becomes warm. ✅ In subtropical High Pressure belts (around 30° North/South), The air sinks . Clear skies form (no clouds). Strong sunlight directly heats the land → very high temperatures . But still, pressure remains high because of the sinking movement . ✅ Therefore, deserts like Sahara, Kalahari, Thar, Atacama are located under High Pressure belts , even though they are extremely hot. ✅ At 30° N/S (subtropical regions), Air sinks → High Pressure (HP) → Clear skies → NO rain → Deserts form (like Sahara, Thar, Australian deserts). Now your confusion : "If deserts are hot, isn't hot air Low Pressure (LP)?" 👉 Answer: Deserts are hot because of strong sunlight. BUT the pressure is still High , because the air is sinking and piling up on the ground. The heat is due to sun and clear skies (no cl…
