We will know and understand the history of

weather forecasting, and

modern techniques used,

such as Doppler radar.

We will know the effects

of tropical climates on

Earth’s overall weather.

We will know the impact

of weather events and

how they affects earth

and it’s population

The history of weather

forecasting begins with the civilization of

the Babylonians who

were the first civilization believed to

attempt forecasting weather. They would

observe the clouds and other visual atmospheric phenomenon, in 650

B.C.

The first known text

on weather forecasting was written by Aristotle. The treatise was called

“Meteorlogica”. Almost all of it has been disproven today,

but for the time it was

the only book trying to

explain weather in a

scientific way.

A lot if not most of

the tools used today

to forecast weather were invented in the

renaissance. The following tools all stemmed from inventions made during the renaissance.

Modern

tools A Hygrometer is tool

created in the renaissance for being

able to tell atmospheric humidity.

It has been improved

upon but is still used

today in almost the same form

Modern

tools

A Barometer is a device also created in

the renaissance that

pretty much hasn’t aged. The device is used to measure atmospheric pressure

Modern

tools

An Anemometer is an

instrument used to measure wind speed(this one may have also been invented during the renaissance but that is

heavily debated)

Tropic

al C

limate

s

Tropical climates are large

areas of high temperatures

and year around rainfall.

Tropical climates will have

high humidity rates along

with a massive amount of

vegetation.Due to the amount of heat

and oxygen given of by

these climates, they will

have a drastic effect on

Earth’s weather and

climate.

Eff

ect

s

Along the equator is where most of

the tropical rainforest are located.

Thanks to the solar radiation given

off by the sun, these areas

accumulate a large amount of

excess heat. This heat is transferred

through out the globe by winds and

ocean currents.When this heat reaches new climate

zones it will begin to effect the

atmosphere and biosphere of these

different climates. When the warm air from the tropics

mixes with cooler air from the

oceans different types of tropical

storms are created including,

hurricanes, typhoons, and not

tsunamis.

Thunder: a loud, explosive, resounding

noise produced by the explosive

expansion of air heated by a lightning

discharge.Thunderstorm: a transient storm of

lightning and thunder, usually with rain

and gusty winds, sometimes with hail or

snow, produced by cumulonimbus clouds.

Lightning: an electric spark discharge in

the atmosphere, occurring within a

thundercloud, between clouds, or

between a cloud with the ground.

Tornado: an extremely destructive funnel-

shaped rotating column of air that passes

in a narrow path over land.

Hurricane: a violent, tropical, cyclonic

storm of the western North Atlantic,

having wind speeds of or excess of 72

miles per hour

One of the biggest disasters

in hurricane history, category 2 Katrina’s destruction left 1836 people

dead and an unknown

amount of people missing.

Left America with economic,

environmental, social, and

political effects.Katrina was the costliest

hurricane in U.S. history with

the losses amounting to

more than 89.6$ Billion of

damages
