Climate
Climate means the usual condition temperature , humidity , atmospheric,
pressure, wind, rainfall, and
meteorological element in area of the earth surface for a long time in
simple terms climate is the a condition for about thirty year.
According
by prof A Balasubra manian state that climate of a region is ultimately
determined by the radiation energy of the sun and its distribution and temporal
fluctuations the long term state of interacting element they solar radiation
Air masses, pressure system and cyclone belts ocean currents Topography.
Weather is
the condition of atmosphere take over short period of time. weather are
different element contain of the surface there are temperature, humidity, precipitation,
pressure ,wind, and cloudiness.
CHARACTERISTIC
OF ELEMENT OF WEATHER AND CLIMATE.
1. Temperature.
is the degree of hotness and coldness of the atmophere.Temperature is a very important factor in determining the
weather because it influenced or control other element of the weather such as
precipitation, humidity, clouds, and atmospheric pressure.
2. Air masses. Wind and storms an air mass is a
large body of air with generally uniform temperature and humidity. Air masses
control the characteristics of temperature to source regions of air masses in
party determined the variation of the day to day weather and long term climate
of a place. The movement of the atmosphere is called wind
Wind can be felt only when it is in
motion.
. Wind is the result of the horizontal
differences in the air pressure.
Wind is simply the movement of
air from high pressure to high pressure of low pressure and the difference
between high and low pressure.
The
wind brings with it temperature of the area it is coming from therefore a high
pressure in a warm region will make the temperature in the low pressure area
higher.
3. Pressure
systems.
Air
pressure is the weight of air resting on the earth surface. Air has specific
weight this weight exerted by air is atmospheric pressure. Pressure it is
defined as the force per unit area exerted against a surface by the weight of
air above that surface in the earth atmosphere pressure system has a direct
impact on the precipitation.
4. Ocean
current. are greatly affect the temperature and precipitation of climate, those
bordering cold currents tend to be driver
as cold ocean water helps stabilize the air and inhabit clouds formation
and precipitation of air traveling over Cold ocean currents lose energy to the
water and thus moderate the temperature of nearby coastal location.
Air
masses traveling over warm ocean currents promote instability and precipitation
additionally the warmer ocean water keeps air temperature somewhat warmer than
location just in Land from the coast during the winter.
5. Humidity. Atmospheric moisture is the most
important element of the atmosphere which modifies in the air of the lower atmosphere.
There are three types of humidity.
(a)
Absolute humidity .the amount of water vapor present in per volume of air at
definite temperature.
(b)
Relative humidity. is the ratio of water vapor present in air having a definite
volume at
6. Visibility.
the most critical weather element obstruction to visibility includes clouds fog
smoker haze and precipitation. Visibility represent by the meteorological
optical range mon.varries with the back ground illumination. in extremely clean
air in Arctic or mountainous areas the visibility can be up to 70kilometer43mto100kilometers
. Visibility is often also reduced somewhat by air pollution and high
humidity.
7. Topography.
Topography affect climate in variety of ways the orientation of mountain to the
prevailing precipitation wind ward slopes those farcing into the wind
experience more precipitation due to orographic up lift of the air Lee Ward
sides of mountain.
8. Cloudnnes,clouds are suspended water in the atmosphere cloud are
usually the most obvious feature of the sky clouds give us a clue about what is
going in atmosphere and how the weather might change in the hour or even days come.
each type of clouds form in different way and each brings it's own kind of
weather clouds play multiple critical role in climate.
CONTROLS OF CLIMATE AND WEATHER.
1
L.atitude,these are the main factor influencing the climate of region is
latitude because different latitude receive different amount of air the earth
rotation on its axis changes the angle of sun light at certain latitude therefore
changing the temperature at that latitude this has major impact of
temperature.
2. Land and
water distribution, land and water heater and cool at different rates land heat
up faster and gets hotter than water land also cool faster and to lower
temperature than water this is moderate effect of temperature.
3. Ocean current, the temperature of the water
off shore influences the temperature iof coast location particular if the winds
come of the sea the cool water of along the western United States is caused by clockwise
rotating ocean currents that is bringing cold water from the arctic toward the equator.
4. prevailing wind, the prevailing wind are the
bases of the bases of the Hadley,frrelle and polar cells these wind greatly
influence the climate of a region because they bring the weather from the
location they come from example in California the predominant winds blowing in
from pacific ocean which bring in Relative cool air in Winter local wind also
influenced local climate for example land breeze and sea breeze.
5. ,altitude,
air pressure and air temperature decrease with altitude the closer molecule are
packed together the more likely they are to collide collision between molecule
give off heat which ms the air at higher altitude the air is less dense and air
is less sense and air molecule are more spread out and less likely to
collide.
Generally
are the characteristic of weather and climate and control of weather but
weather and climate are very important in our life through this it help to know
about the change of weather example in summer
condition this was know the condition of this period and during the
winter it help to know the climatic change of the area
