Report on Wind :: Wind Energy Weather Essays

Report on Wind I did my report on wind. As you may or may not know wind moves horizontally, and the wind that doesn’t move horizontally moves vertically. That kind of wind is called a current. Many things may cause these rushes of moving air, one thing would be atmospheric pressure differences. The differences in the distribution of pressure and temperature is caused by the unequal distribution of heat. There are also the differences in the thermal properties of land and the ocean surfaces. When the temperatures of different regions become unequal, the warmer air will normally rise and move over the cold air because the cold air is heavier. That will sometimes cause things like tornadoes. Another way that winds move are by the usually great rotation of the earth. Isn’t that enough as it is? Really though†¦..how fast are we rotating and flying through space? Winds are classified into four major types believe it or not. The four major groups are, the local winds, the seasonal winds , the cyclonic and anticyclonic winds, and the prevailing winds. That’s kind of impressive if you ask me! Most people think of wind as a slight breeze on a summer’s day when it could be so much more. There are actually many, many more kinds of wind. You must remember that those are just the four main kinds. Now back to our "summer’s breeze," the strongest wind ever reliably measured on the surface of the earth was 362 km per hour or 225 miles per hour, recorded on Mount Washington, New Hampshire, on April 12, 1934. Considerably stronger winds, however, occur near the centers of tornadoes. I also thought that that was pretty neat. I got that fact out the Encarta ’95 encyclopedia, a very reliable source. That’s where I got a lot of the information in this report. Now we get the chance to talk about the local winds. These winds are determined by the seasonal changes in temperature and pressure over the land as well as water. During the day changes occur, which will exercise a similar but more of a local effect on places. These changes that will only occur during the day are diurnal. These diurnal occurrences happen mostly in the summer, because the land is warmer than the surrounding water during the day and is colder than the water by night. Isn’t it strange? O’well. The variations of pressure therefore lead or move a called forth system of breezes directed toward the land during the daytime and back towards the sea at night.
