.... and landing regime (Harpool 2). The key to understanding development of wind shear below the bases of convective clouds is a good knowledge of the characteristics of a typical precipitation-induced downdraft. Not all precipitation-induced downdrafts are associated with critical wind shears. However, there are two types of down drafts that are particularly hazardous to flight operations because of there severity and small size. Professor T. Fulita, an atmospheric scientist from the University of Chicago, coined the term downburst for a concentrated, sever downdraft that induces an outward burst of damaging winds at the ground. He also introduced the term microburst for ....

.... divides the oxygen molecule (O2). Each molecule then attaches with other oxygen molecules to form O3. O3 is ozone. So when ozone is formed, harmful rays from the sun are absorbed. The O3 molecule is very reactive and it bonds easily with other molecules it the atmosphere. When and oxygen atom from the ozone reacts with a chloride ion from chlorine monoxide, the ozone molecule is destroyed. So chlorine monoxide is an ozone destroyer. There is always a certain amount of chlorine monoxide in the atmosphere. It is important to remember that ozone is constantly being created and destroyed in the atmosphere. The amount of ozone in the atmosphere is based on these reactions. The ....

.... new primary energy source that is environmentally benign. This source is renewable energy and is already readily available. The increased use of renewable energy, mainly wind and solar energy, and reduction of dependence on oil is the best way to solve our current energy dilemma. For the past fifty years, fossil fuels have been the main source of energy in the U.S. They are a great source of power, but unfortunately they also have many setbacks. The finite reserves of fossil fuels are being depleted at a rate one hundred thousand times faster than they are being formed. As supplies decrease we become more and more dependent on the Middle Eastern countries for our supplie ....

.... their final hour then we are actually improving their life. If you feel that saving a person’s life is a bad thing, then I’m sorry. People often question whether or not we have the right to clone. We are all guaranteed rights by the fact that we are human beings. Those rights include the right to pursue areas of scientific study, and also the right to live. They could have argued the fact that man was not meant to walk on the moon. If they did, and the program did not succeed, then we would not have the technology that we have today. Cloning organs can only yield new technologies that will be beneficial to society. Organ cloning is something that would be extremely benef ....

.... certain areas which will soon be their careers. But, to the computer illiterate, everyday brings new challenges in the vast, unknown realm of the computer. They ask, “What is this thing called e-mail, and how does it work?” What are they to do when a teacher assigns the students to send in all assignments by e-mail? Eventually, they will have to learn the basics of e-mail which, in turn, reveals even more problems with being computer illiterate. For an essay, the teacher requires that they go to the library to do research. The computer illiterate happily walks into the library to do their research. Imagine their surprise when they find out that the main tool of ....

.... convergence zone and rises to the poles. There the air is cooled and it floats back down to the equator where the process is repeated. Another major contributing factor to the circulation of the air is due to the subtropical highs. These highs like the ITCZ migrate during the different seasons. The idealized belt model is a great representation of the general circulation of the atmosphere. The equatorial belt of variable winds and calms ranges from 5 degrees north to 5 degrees south. This wind belt is characterized by weak winds and low pressure from the inter tropical convergence zone. As you go further north or south you encounter the ....

.... crops from a variety of different pests. This is why DDT is known as the most effective pesticide ever produced (Ray 71). It is proven to have been the most effective chemical ever to prevent the spread of malaria all over the world. It nearly wiped out the disease in some countries altogether. It has been repeatedly proven that DDT does not cause any form of cancer in humans. Contrary to what environmentalist attacks on the pesticide have alleged, the benefits of DDT far exceed the flaws. DDT was first synthesized in 1887 and patented as an insecticide in 1939 by a Swiss chemist, Dr. Paul Müller (Whelan 69). It initially became popular because of its effectiveness a ....

.... who have little education, the truth is, we all are targets. One form of that plaques our society is called major . Major is a mood disorder characterized by extreme and persistent feelings of despondency, worthlessness, and hopelessness causing impaired emotional, cognitive, behavioral, and physical functioning (Hockenbury & Hockenbury, 1998). Major affects about 12 million American a year (Hockenbury & Hockenbury, 1998). Individuals who suffer from this form of is overwhelmingly sad. Often, sadness is accompanied by feelings of quilt, worthlessness, inadequacy, emptiness, and hopelessness, even though these individuals are surrounded by friends and family, they feel ....
