If in that location is equal water or ice , there will be heedlessness (Williams , 2008Indeed , pressure in the air plays a resilient assort in influencing the weather condition . This is the reason wherefore atmospheric pressure is a rouge indicator of weather changesReferencesPressure (2000 . cyclopaedia of Atmospheric Environment .
