Natural ventilation in domes structures.
"A windtower (wind catcher) (Persian: ???????? bâdgir: bâd "wind" + gir "catcher"[1][unreliable source?][2]) is a traditional Persian architectural element to create natural ventilation in buildings.[3] Windcatchers come in various designs: uni-directional, bi-directional, and multi-directional. Windcatchers remain present in many countries and can be found in traditional Persian-influenced architecture throughout the Middle East, including in the small Arab states of the Persian Gulf (mostly Bahrain and Dubai[4]), Pakistan, and Afghanistan."
