2 Weather, Climate, Climate Change, and Air Pollution
Control
Weather is the specific condition of the atmosphere at a particular place and time. It
is measured in terms of such things as wind, temperature, humidity, atmospheric
pressure, cloudiness, and precipitation. In most places, weather can change from
hour to hour, day to day, and season to season. Climate in a narrow sense is usually
defined as the “average weather” or, more rigorously, as the statistical description in
terms of the mean and variability of relevant quantities over a period of time ranging
from months to thousands or millions of years. The classical period is 30 years, as
defined by the World Meteorological Organization (WMO). These quantities are
most often surface variables such as temperature, precipitation, and wind. Climate in
a wider sense is the state, including a statistical description, of the climate system. A
simple way of remembering the difference is that climate is what you expect (e.g.,
cold winters) and “weather” is what you get (e.g., a blizzard).
Climate in a narrow sense is usually defined as the “average weather” or, more
rigorously, as the statistical description in terms of the mean and variability of
relevant quantities over a period of time ranging from months to thousands of
years. The classical period is three decades, as defined by the World Meteorological
Organization (WMO). These quantities are most often surface variables such as
temperature, precipitation, and wind. Climate in a wider sense is the state, including
a statistical description, of the climate system. It is the average weather (usually
taken over a 30-year time period) for a particular region and time period. Climate is
not the same as weather, but rather, it is the average pattern of weather for a
particular region. Weather describes the short-term state of the atmosphere. Climatic
elements include precipitation; temperature; humidity; sunshine; wind velocity;
phenomena such as fog, frost, and hail storms; and other measures of the weather.
Climate change means the changes in average weather conditions that persist over
multiple decades or longer. Climate change encompasses both increases and
decreases in temperature, as well as shifts in precipitation, changing risk of certain
types of severe weather events, and changes to other features of the climate system.
Climate change refers to any significant change in the measures of climate lasting for
an extended period of time. In other words, climate change includes major changes
in temperature, precipitation, or wind patterns, among others, that occur over several
decades or longer. It is believed that air pollutants, known as greenhouse gases,
cause the climate change. One of the objectives of this study is to determine (a) the
effect of climate change and (b) whether or not proper air pollution control may
prevent the climate change.
The addition into natural air of any harmful or objectionable substances, or
energy (heat, chill, radioactivity, wavelength), or noise, in large enough quantities
to adversely affect the natural air’s usefulness is air pollution. We must control these
objectionable substances, or energy, or noise, in order to protect our precious
environment and its natural resources. We neither need excessive global warming
nor climate change.
