Introduction of
Meteorology
Objectives
• To describe, in your own words, what the word
meteorology means.
• To describe, in your own words, what a
meteorologist is.
• To describe, in your own words, what weather is.
• To describe, in your own words, what a climate.
• To describe, in your own words, the difference
between weather and climate.
What is Meteorology?
• It is the scientific study of all changes in
the atmosphere. This is very useful for
weather forecasting.
What is a meteorologist?
• A person who studies changes in the
atmosphere. This person may forecast the
weather.
What is weather?
• The four main components which cause
weather are the Sun, the atmosphere,
water vapor and the wind.
• These all work together, spreading the
Sun’s heat around the world and making
clouds, rain and snow.
• Weather is an endless cycle of events.
Where does it happen?
• The atmosphere is like a giant blanket of
air around the Earth.
• It is divided into layers. Weather happens
in the troposphere, the layer directly above
the ground.
We will learn more about he atmosphere in
lesson 2.
Here are the 5 major weather
elements:
• Air Temperature
• Wind
• Humidity
• Pressure
• Rainfall
So why are there changes in these five
elements?
• The scientific study of climate and
weather- Meteorology will explain why.
Can you name different types of
weather?
Climate and Weather
• We will begin our study of the weather by
learning the difference between the word
“weather” and the “word climate.”
Weather
• Weather is what happens outside day to
day based on the seasons and other
factors.
Climate
• Climate is the pattern of weather that
occurs over a long period of time in a
particular area or region.
– Desert or arid
– Tropical
– Polar
– Forrest tundra
– Temperate
– Mountain
Desert/Arid
• Arid climates can be found on every continent. They
range from hot and dry deserts that see almost no rain to
semiarid scrub land where rain falls intermittently. Arid
climates are not suitable for most life forms. Plants and
animals that make their homes in arid climates have
made special adaptations to the environment.

Tropical
• One of the classifications is that of tropical wet
climates, or rainforests. Humid tropical climates
have distinguishing characteristics other than
temperature and precipitation. Tropical humid
climates have distinct locations and abundant
animal and plant life.

Polar
• Polar climates remain very cold throughout the year with
temperatures ranging between negative 70 degrees and 20 degrees
Fahrenheit. Physical characteristics of polar climates include
glaciers and thick layers of ice on the ground. The different kinds of
polar climates include tundra climates and ice cap climates. Tundra
climates have at least one month in a year when the average
temperature is above freezing levels. The coldest temperatures in
the world are found in Antarctica, which is an ice cap climate.

Tundra
• The tundra climate is found along arctic
coastal areas. Polar and arctic air masses
dominate the tundra climate. The winter
season is long and severe. A short, mild
season exists, but not a true summer
season. Moderating ocean winds keep the
temperatures from being as severe as
interior regions.
Forrest
• This is a continental climate with long, very
cold winters, and short, cool summers.
This climate is found in the polar air mass
region. Very cold air masses from the
arctic often move in. The temperature
range is larger than any other climate.
Precipitation increases during summer
months, although annual precipitation is
still small.
Temperate
• Temperate climates, otherwise known as meso-thermal
climates, are cooler than subtropical climates, but
warmer than polar climates. The moderate oceanic
climate is a sub-type of temperate climates. The regions
have fresh summers and wet winters with mild weather.
A continental moderate climate is another sub-type of
temperate climates. These regions have hot, rainy
summers and cold, dry winters.

Mountain
• Alpine climates are similar to tundra climates because
they are both cold and dry throughout the entire year.
The annual precipitation of alpine climates is about 30
centimeters (about 12 inches) per year. These climates
are found at the tops of mountains, which are vacant of
any trees, other than dwarf trees. Other plants found in
alpine climates include tussock grasses, heaths and
shrubs.
