the gaseous envelope that surrounds the Earth

Is the atmospheric conditions of an area for a short period of time and depends upon the climate of the area.

is the atmospheric conditions of an area over a long period of time and characterized by different kinds of weather.

the intensity of degree of heat

a circular portion of the atmosphere having a relatively low barometric pressure around.

seasonal winds caused by extreme heating and cooling of large land masses.

is the science which deals with the study of the atmosphere and it's phenomena.

- is the branch of Meteorology which is connected with the study and influence of synoptic phenomenon in space, based on analysis of charts on which plotted synoptic observations for the purpose of weather analysis and forecasting.

- the sloping boundary surface separating two opposing air masses having different temperatures.

- means the incoming solar radiation or the portion of the solar radiation received by the Earth at its atmosphere.

is a meteorological phenomenon characterized by an abrupt change of wind direction and speed, a sudden rise in pressure and relative humidity, a sudden fall in temperature and often by precipitation which may take the form of thunder showers.

- the state of the atmosphere when it holds the maximum amount of water vapor possible at a particular temperature (saturation point).

the unit used to express the average pressure of the atmosphere at sea level.

lines in a weather map connecting places with equal barometric pressure.

- the term used for the moisture in liquid or solid form that fall to the earth from the clouds.

origins from the water evaporated in the air and becomes saturated.

- the process of changing liquid into vapor.

refers to the direction from which the wind is blowing.

the temperature of the atmosphere at which the water condenses.

the general term use to indicate the amount of water vapor present in the atmosphere.

- the process which heat is transferred from one molecule to another without transfer of the portion of the matter itself.

weather maps, a line joining all places having the same air temperature.

the greatest distance at which an object or specified characteristics can be seen and identified in any particular circumstances.

is the process that leads to the formation of fronts.

is the process leading to the decay or dissolution of fronts.

- is the unsteadiness of the mercury in the barometer caused by swinging the instrument, or by fluctuating in the air pressure produced by gusty winds or by heaving of the ship.

is a marked transitional zone of a quasi- permanent character between the tropics, which separates the northern trade winds, or constitutes the extreme limit of monsoon.

a curved line on a weather chart joining all places having the same change of barometric pressure in a standard interval (usually 3 hours) during passage of a cyclonic or anticyclonic wind system

the vertical distance between the earth and the base of a cloud.

an instrument which measures the humidity.

an instrument which measures the wind velocity.

an instrument which measures the atmospheric pressure.
