PPT-Winds

The movement of air in a horizontal direction What is wind The uneven heating of the Earth causes differences in air pressure What causes wind The Suns energy is more concentrated at the Equator and spread out more over the poles. Objective. Reconcile the . conflicting evidence of the meridional westerly wind shift during the Last Glacial Maximum (LGM) indicated . by proxy-records from the . atmosphere . and . ocean. Approach. by: . chabrail. Jones, Sophie Ilunga. Definition of a blizzard. A . blizzard. is a severe snowstorm characterized by strong sustained winds of at least 56 km/h (35 mph) and lasting for a prolonged period of time — typically three hours or more.. . climate . CALENDAR. . January|. January coincides with the peak of the rainy season in Seychelles. It is an extremely wet and humid month with occasional outbreaks of showers day or night with a slight preference for rain in the late morning/afternoon hours. These showers are sometimes accompanied by thunderstorms.. G. VanNada. What are they?. Tropical cyclones that cross the subtropical ridge axis into the Westerlies recurve due to increased westerly flow. The winds are predominantly from the southwest in the Northern Hemisphere and from the northwest in the Southern Hemisphere. i. What causes wind? . Caused by a difference in air pressure due to. unequal heating of the atmosphere.. Winds are created by. ….. • . Heating the air, decreases pressure (warm. air rises creating a low pressure).

When you open the valve on a bicycle tube, the air rushes out.. Science. Thunderstorms & Lightning. Conditions That Occur During Thunderstorms. Thunder, lighting, high winds, heavy rain, hail. Electric Sparks by Shuffling . Lightening is like electric sparks that you can make by shuffling across a carpet before touching a metal object. Both lightning and small electric sparks are discharges of built up static electricity. . Lucrezia Ricciardulli, Thomas Meissner and Frank Wentz. Remote Sensing Systems, Santa Rosa, CA, USA.

Reconcile the . conflicting evidence of the meridional westerly wind shift during the Last Glacial Maximum (LGM) indicated . by proxy-records from the . atmosphere . and . ocean. Approach. Compare & contrast an idealized hurricane life cycle with a real life example from the past. Understand how the angle of approach of a storm impacts regional damage. Objectives. Hurricane Structure.

Heating the air, decreases pressure (warm. air rises creating a low pressure). Wind is the movement . of air caused by an uneven heating of the Earth’s . surface.. What HEATS EARTH’S SURFACE?. Heat from the sun heats the surface of the Earth.. This heat arrives to Earth in the form of radiation.. Global . Winds. - A . current. is a flow of air or water in a certain direction.. Global . Winds. Winds move from areas of . high. pressure to . low. pressure.. You might expect them to move straight from the poles (high pressure) to the equator (low pressure)but….
