Understanding Convectional Rainfall

Convectional rainfall occurs when the energy of the sun (or insolation) heats the earth’s surface and causes water to evaporate changing to water vapor. This warm, moist air then rises, and as it rises, it cools. The air reaches a point called the condensation level where it has cooled to such an extent that the water vapor condenses and turns back to a liquid form. This process of condensation high in the atmosphere leads to the development of clouds. As the clouds continue to grow the weight of the water droplets can eventually lead to precipitation. (You can see the cycle in this diagram.) Convectional Storms Convectional storms occur in many areas of the world. They are at their most severe in parts of the tropics where there is a water source and intense heating. They are also common in warm mountain areas like the European Alps in the summer. This photograph shows the towering cloud developed by strong rising air currents. This convectional storm occurred near Sydney in 2002. There was heavy rain and hail. Hailstones develop when ice particles form in the cloud. The currents of air move the particles up and down in the cloud and as this happens additional layers of ice form around the nucleus. Eventually, the hailstones become  too heavy to be kept up, and they fall to the ground. This website has some useful photographs and video clips. Convectional storms  affect people’s lives in many ways. They can present various hazards to aircraft including turbulence and freezing at high altitudes. The following is based on an extreme weather summary for south Kansas in the USA. Source: Kansas 2006 http://www.crh.noaa.gov/ict/newsletter/Spring2006.php The convective storm started when hail 5 to 10 cms diameter hit a number of rural counties. Between 6:00 and 7:00 pm, one of the super-cellular severe storms in Reno County unleashed its power and caused disastrous and tragic results. The storm produced 80-100 mph winds on its southern end which raked south and southeast Reno County. This storm then took aim at Cheney Lake and State Park. The damage at the state park was major, and included the marina, around 125 boats, 35 campers, and an unspecified number of mobile homes. One mobile home was leveled. Total damage estimated around 12.5 million dollars. Six people were injured, all of whom required transport to Wichita hospitals. One man was killed when his fishing boat was overturned. On June 30th, Southeast Kansas was hit by destructive winds and hail that reached the size of baseballs. The baseball-sized hail hit parts of Woodson County around 7:35 pm, causing around $415,000 damage to crops. As the evening progressed, the severe thunderstorms, continued to unleash 80-100 mph winds. Hardest hit was Neosho County. In Chanute, large trees were uprooted with many falling onto homes and businesses. Other homes and businesses were completely unroofed. Numerous barns and sheds were destroyed. The towns of Erie and St. Paul experienced nearly identical fates. In Erie, one home was destroyed. In St. Paul, a church steeple was completely removed. Obviously, many power lines and power poles were blown down, severing power to all three towns. This round of atmospheric mayhem was responsible for $2.873 million damage to crops and property. Another product of severe convection that drew considerable attention in 2005 was the flash flood. The first major event occurred June 8th and 9th from around 8:00 pm the evening of the 8th to the early afternoon of the 9th. Hardest hit were Butler, Harvey and Sedgwick counties. In Butler County, two families required rescues from their homes 4 miles north of Whitewater. Numerous streets were barricaded in and around El Dorado, and creeks overflowed. The most notable occurred 2 miles northeast of Elbing, where Henry Creek overflowed, closing 150th Street as well as the 150th Street Bridge. In Harvey County, widespread 12-15 inch rainfalls in approximately 10 hours resulted in evacuations in Newton, where most streets were barricaded. Perhaps the worst flooding in this event occurred in Sedgwick, where an estimated 147,515 acres of farmland were inundated totaling an estimated $1.5 million damage. In Sedgwick County, 19 homes were flooded, of which 12 were mobile homes which are particularly susceptible to storm damages. These homes were completely surrounded by flooding; which isolated their occupants from the outside world. In Mt. Hope, people required rescue from their homes. Many streets and highways were barricaded, especially across Northern Sedgwick County, where flash floods reached 6 foot depths. The flooding inundated around 75,000 acres of farmland. Total property damage was estimated at $150,000.    ACTIVITIES Study the article above.

The Guardians Of The Flutes - 924 Words

Human sexuality can be interpreted in many different ideas and understandings. Watching the documentary â€Å"Guardians of the Flutes,† I was able to see a different life style than I’m use to but at the same time see many similarities. Both men and women have different roles in their daily lives and their works do not intersect. The Sambia tribe is patriarchal, in which the men have the control or rule, similar to most American house hold; however, that is changing. Understanding the way sex influences or impacts our lives is very important. Not only do humans interact sexually but also many animals. Human sexuality is being able to be comfortable with one to be able to interact with others in a deeper level. The Sambia tribe treats sex as something dirty and unpleasable but rather than a way to show their masculinity. Also, they go very far into the forest to be able to engage in sexual activity. In my option the Sambia lack sexual literacy. According to Herdt, In ord er to become sexual literate, â€Å"†¦you can develop healthy and positive attitudes in your thinking, communication, and lifestyle that will result that in satisfying sexual relationships when you decide you’re ready for sexual intimacy.† The men was more open to sexual activities and engaged at a very young age but for a women they had to wait until marriage.

While using the computer a person can have a friend in Russia or talk with tango dancers from Argentina. What is more online friends do not judge weight, skin color or clothes. Despite the pluses which were mentioned above, one of the major disadvantages of virtual communication, especially at the beginning of new acquaintance is that anyone can enhance the truth as much as he wants. Not all sites require a photo, and even those that do cannot guarantee that the photo is a real one. Clear signs that the photo may be a fake are strange backgrounds that might indicate a stock image, photos that appear professionally taken and photos that seem old rather than current. Unfortunately some people are not able to identify counterfeit images therefore the internet makes it easy to lie, thus in some cases almost impossible to discern whether the ad is honest or the truth is being embellished. Furthermore, relations through the internet reduce or eliminate face-to-face socialization.

Unfortunately, this feature of online socialization cheats people of the opportunity to learn how to resolve conflicts in the world outside the Internet and it could retard or cripple one’s social skills developments. A report from the National School Boards Association shows that 41 percent of teenagers spend their time posting messages instead of face-to-face interactions with their peers. In conclusion, although the extension of virtual influence is increasing day by day, the real human interactions will not be replaced among society.
