1

Air pressure

Atmospheric pressure is the force per unit area exerted by the weight of the atmosphere To measure that weight meteorologists use a barometer Atmospheric pressure forces the mercury to rise up the tube. At sea level, the column of mercury will rise (on average) to a height of 29.92 inches or 760 millimeters.

2

Tropical

is something related to the tropics - the warm, hot areas located between the Tropic of Cancer and the Tropic of Capricorn. Warm and humid weather often associated with the tropics is an example of tropical weather.

3

Celsius

or relating to a temperature scale that registers the freezing point of water as 0° and the boiling point as 100° under normal atmospheric pressure. See Table at measurement.

4

Cumulus Cloud

are clouds which have flat bases and are often described as "puffy", "cotton-like" or "fluffy" in appearance. Their name derives from the Latin cumulo-, meaning heap or pile.[1] Cumulus clouds are low-level clouds, generally less than 2,000 m (6,600 ft) in altitude unless they are the more vertical cumulus congestus form. Cumulus clouds may appear by themselves, in lines, or in clusters.

5

Cirrus Cloud

Cirrus is a genus of atmospheric cloud generally characterized by thin wispy strands giving the type its name from the Latin word cirrus meaning a ringlet or curling lock of hair.

6

Thermometer

Is an instrument for measuring and indicating temperature

7

Tropical Depression

Is A tropical depression forms when a low pressure area is accompanied by thunderstorms that produce a circular wind flow with maximum sustained winds below 39 mph

8

Ocean current

Is An ocean current is a seasonal directed movement of sea water generated by forces acting upon this mean flow such as wind the Coriolis effect breaking waves cabbing temperature and salinity differences while tides are caused by the gravitational pull of the Sun and Moon.

9

Dew point

Is the atmospheric temperature varying according to pressure and humidity below which water droplets begin to condense and dew can form

10

Hurricane

Is a storm with a violent wind in particular a tropical cyclone in the Caribbean

Desert

Is abandon a person cause or organization in a way considered disloyal or treacherous

Tornado

Is a mobile destructive vortex of violently rotating winds having the appearance of a funnel shaped cloud and advancing beneath a large storm system

25

Cumulonimbus

Is a cloud forming a towering mass with a flat base at fairly low altitude and often a flat top as in thunderstorms

26

Thunder

Is a loud rumbling or crashing noise heard after a lightning flash due to the expansion of rapidly heated air

Is a rotating column of water and spray formed by a whirlwind occurring over the sea or other body of water

29

Barometer

Is an instrument measuring atmospheric pressure used especially in forecasting the weather and determining altitude

30

Global Warning

Is a gradual increase in the overall temperature of the earth's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide chlorofluorocarbons and other pollutant
