A zinc coating, usually hot-dipped, in which the zinc and steel form a metallurgical bond. The thickness of a hot-dipped coating can be varied from a thin zinc/iron alloy layer to heavy applications suitable for extended outdoor exposure.
Humid subtropical climate. In Africa, the humid subtropical climates are found in two separate areas on the southern hemisphere of the continent. The Cwa climate is found over a large portion of the interior of the Middle and Eastern African regions.
The tropical climate is then a place of warm low pressures. This is where you find the rain forest belt around the earth. The subtropical climate is then the belt around the earth where you find warm but dry air because it sinks.Those are the high pressures are roughly latitudes 30. That is where you find most deserts around the earth. The front at latitude 60 is then the front between polar and subtropical air masses.The latter climbs over the former because warmer and the process decreases the pressure thus forming low pressures.hat is where you find most deserts around the earth.
