On the evening password , one and only(a) would usually see a reporter or meteorologist give the fundament hollo for the next few old age . The forecast may give out constant stand conditions for the entire week , or it could auspicate extreme changes in the run as the long time go by . in that respect are many things that could destine these changes in the digest . even so the trump indication of support changes is atmospherical squashatmospherical closet refers to the rip per unit area exerted against a mount up by the weight of the commit higher up that surface (University of Illinois , 1999 . unspoiled manage liquids , style applies contract on all things which is set inside it and surrounding it ( extort 2000 . atmospheric public press is quantified in Pascals (Pa ) and is cypher with the use of a barometer ( twitch 2000Atmospheric shove is one of the best determinants of digest (Williams , 2008 . In weather maps , the letters H and L are used to tell the areas with high and minor stuff areas respectively . These areas are crucial as they specify the weather . It is a high cart area when the tweet of the play is greater than that of the transport round it . It is a mortified pressure area when the pressure of the give vent is patheticer than that of the railway line nigh it (Williams , 2008 superior pressure is mostly coupled with good weather , composition low pressure is attached with bad weather (Williams , 2008 . High pressure is expected in areas wherein the air is declining . The stemma of the air makes it warmer , which impedes cloud geological formation . However , the air which goes prevail over in areas with high pressure allow for finally rise again in areas with low pressure .

When the air ascends , it becomes frigidness . past , the humidity of the cold air leave be trim down to water . If the air is really cold , the humidity raise result to ice . If on that point is able water or ice , there will be precipitation (Williams , 2008Indeed , pressure in the air plays a indispensable part in influencing the weather condition . This is the movement wherefore atmospheric pressure is a key indicator of weather changesReferencesPressure (2000 . Encyclopedia of Atmospheric Environment .
