This essay Weather Forecasting has a total of 919 words and 5 pages.
In researching this project I was amazed to find the many books on this
topic. After going through much information and reading an enormous amount of
writing on weather forecasting I can only come to one conclusion that when all
is considered the best forecasters can only give an educated guess of what is in
store for weather. Through the many means at their disposal, such as satellites,
ships at the ocean, infrared, radio, and radar transmissions even with all of
these techniques no prediction is 100% accurate.
One question that I asked myself was "when was the first weather
forecasting ever done?", I found out that in 1863 in Britain there was a united
forecasting system headed by Captain Robert Fitzroy. Captain Fitzroy would send
ships around Britain to warn people of storms and such. However, he was often
wrong and criticized and therefor committed suicide. Since then there have been
many other services, but the largest one currently is the National Weather
Service. The National Weather Service gives predictions for all of the world
through satellite imagery for all countries. Also in recent history many local
television and radio stations have made private forecasts for small areas.
Meteorologists are people who interpret the weather, the reason I don't
say predict the weather is because even though all forecasters have the same
information and data at their fingertips, the way that they interpret what is in
front of them can be different. Meteorologists receive information from various
sources, but their interpretation of the data determines the accuracy of their
Someone might ask, "If forecasters have so much information on a
particular area; how could they predict a flawed forecast ?" The answer to
that question lies in the fact that any one of a number of weather conditions
may ruin a forecast. A fast cold or hot front moving in, an unexpected flow
from the ocean or a cold wind may change the whole days forecast.
There are many different materials and devices used by local and
government services to predict the weather. Some of these devices are, Radar
which is actually sound waves, which bounce off clouds and give location of
storms this way.
Another such device is actually a variation of radar called "Doppler
Radar" actually can give the exact location of a storm within a kilometer.
However, Doppler Radar is not used so much for everyday forecasting, but for
tornadoes and very large storms. The way Doppler Radar works is almost the same
as regular radar with one advantage, it also can measure the speed of an object
or storm, which makes its prime usage tornado watching.
Some other techniques have been adapted to forecast the weather such as
infrared beams, which even at night can show where the intensity of a storm is.
And of course there are other instruments used to predict the weather such as
the barometer and the thermometer.
Of course all of these inventions have proven helpful for forecasting
weather, there was still one problem. The main problem was communicating. The
reason for this was that if the forecasters were to send letters to each other
every time there was a storm, their counterparts would not learn of a storm or
tornado for days! The solution to this problem began with the invention of the
The telegraph provided a simultaneous message carrier to anywhere in the
country. Later the radio was invented and then that was used, but still
something else was needed a system to transport footage as well as sound. The
solution to that was solved by the Internet. The internet is a connection by
phone lines which can deliver photos and sound instantaneously.
The next breakthrough in forecasting was the satellite. A satellite
would be launched from Earth and then would take video and photos of the world
and send back to Earth the footage, thereby being able to show storms coming
from the ocean just at the first stages.
The first weather satellite "T.I.R.O.S. 1"the world an infrared view of
the world. However T.I.R.O.S 1 was not specifically built for forecasting but
rather to study clouds. The U.S. government later went on to build 7 more
The first weather satellite truly devoted to weather forecasting was
E.S.S.A. 1 which provided detailed data pictures, and its successor, E.S.S.A. 2
provided pictures from a regular wide angled lens of the world. Furthermore even
though E.S.S.A. and T.I.R.O.S gave birth to a new generation of technological
breakthroughs by toadies standards the information they gave were fuzzy and
incomplete. Later there was a new satellite built in the image of T.I.R.O.S.
called I.T.O.S. which stood for

A Discussion On EarthquakesA Discussion On Earthquakes Perhaps Mother Nature offers no greater force than that of the earthquake. Across the span of time, earthquakes have been recorded for their incredible destructive forces, and their abilities to awe mankind with their unparalleled force. Earthquakes can often strike without any notice, leveling large cities and killing scores of innocent people. Not only can earthquakes bring harm to society through these methods of destruction, but they can also cause millions of dol

Huckleberry Finn - Influences On HuckHuckleberry Finn - Influences on Huck Mark Twain's The Adventures of Huckleberry Finn is a novel about a young boy's coming of age in the Missouri of the mid-1800's. The main character, Huckleberry Finn, spends much time in the novel floating down the Mississippi River on a raft with a runaway slave named Jim. Before he does so, however, Huck spends some time in the fictional town of St. Petersburg where a number of people attempt to influence him. Before the novel begins, Huck Finn has led a li
