2. CHAPTER 2
VARIABLE WEATHER AND CHANGING
CLIMATE
A Continuing Challenge?
In this Chapter you will explore three key
questions:
1.Why do different places experience different
weather and climate?
2.What is happening to the earth’s climate?
3.Is the weather becoming more extreme?

3. Gateway 1: Why do different places experience
different weather and climate?
a. What is the difference between weather and climate?
b. What are the elements of weather?
-Temperature, relative humidity, clouds, rainfall, air
pressure and wind.
c. What are the climatic types and where are they
experienced?

Climate Weather
Definition:
Describes the average conditions expected at a specific
place at a given time.A region's climate is generated by the
climate system, which has five components: atmosphere,
hydrosphere, cryosphere, land surface, and biosphere.[1]
Describes the atmospheric conditions at a specific
place at a specific point in time. Weather generally
refers to day-to-day temperature and precipitation
activity
Components:
Climate may include precipitation, temperature, humidity,
sunshine, wind velocity, phenomena such as fog, frost, and
hail storms over a long period of time.
Weather includes sunshine, rain, cloud cover, winds,
hail, snow, sleet, freezing rain, flooding, blizzards,
ice storms, thunderstorms, steady rains from a cold
front or warm front, excessive heat, heat waves and
more
Forecast: By aggregates of weather statistics over periods of 30 years
By collecting meteorological data, like air
temperature, pressure, humidity, solar radiation,
wind speeds and direction etc.
Determined by:
Aggregating weather statistics over periods of 30 years
("climate normals").
Real-time measurements of atmospheric pressure,
temperature, wind speed and direction, humidity,
precipitation, cloud cover, and other variables
About:
Climate is defined as statistical weather information that
describes the variation of weather at a given place for a
specified interval.
Weather is the day-to-day state of the atmosphere,
and its short-term (minutes to weeks) variation
Time frame: Measured over a long period Measured for short term
Study: Climatology Meteorology

Will we experience snow in Singapore?

9. a. What is the difference between
weather and climate?
Weather: Condition of atmosphere at a
particular place and specific time.
Climate: Average condition of the atmosphere of
a particular place over a long period of
time, usually 30 years.
