Document Summary

Weather is the short term, day-to-day condition of the atmosphere. Meteorology is the scientific study of the atmosphere. Uses radar pulses and looks at the back. Earth"s surface shares its temperature and moisture characteristics with overlying air. Create regional sir masses with similar temperature, humidity, and stability throughout. Distinctive body of air = air mass. Initially reflects characteristics of source region . Classification based upon temp where the air mass starts from. Cp: form only in nh and are most developed in winter (and cold- weather months) Major player in middle and high latitude weather. Cold, dense cp air displaces warm moist air. Area covered by cp air in winter= cold, stable air, clear skies, high pressure, and anticyclonic wind flow. Mp: in the nh these exist over the northern oceans. Aleutian and icelandic subpolar low pressure cells exist within these mp air masses (especially in winter) Mt: two exist that influence north america.
