Answer:
If you are a regular viewer of weather broadcasts, chances are you've heard the following from your local TV meteorologist: “plenty of sunshine is in store today as high pressure is in control over the area.” Or: “expect rain to spread into the area as a low pressure system approache
2- Arctic Circle, parallel, or line of latitude around the Earth, at approximately 66°30′ N. ... The Antarctic Circle is the southern counterpart of the Arctic Circle, where on any given date conditions of daylight or darkness are exactly opposite.
3-the pressure exerted by the weight of the atmosphere, which at sea level has a mean value of 101,325 pascals (roughly 14.6959 pounds per square inch).
4- Air pressure can also change with the temperature. Warm air rises resulting in lower pressure. On the other hand, cold air will sink making the air pressure higher. This is where the terms “low pressure” and “high pressure” come from.
5-What is called a typhoon in the western north Pacific and Asia (Japan) is called a hurricane in north and central America, and a cyclone in other areas of the world. They can be classified into the same meteorological phenomenon in the sense that all have the same type of structure as a tropical cyclone.
6-A cyclonic disturbance in which the maximum average surface wind speed is in the range of 48 to 63 knots (89 to 118 km/h). A cyclonic disturbance in which the maximum average surface wind speed is 64 knots (119 km/h) or more
