If on that point is equal water or ice , there will be over-confidence (Williams , 2008Indeed , pressure in the air plays a resilient circumstances in influencing the weather condition . This is the reason wherefore atmospheric pressure is a unwrap indicator of weather changesReferencesPressure (2000 . cyclopaedia of Atmospheric Environment .
