Weather. Meteorology . Study of atmospheric phenomena Weather – Current state of the atmosphere. Air Density. Like most substances, cold air is more dense than warm air Cold air will sink, hot air will rise. Air Masses.By lilian
Composition of the Atmosphere. The atmosphere mostly consists of nitrogen (78 %), oxygen (21 %), and argon . 99% composed of Nitrogen and Oxygen. Remaining 1% made up of small amounts of other gases. Structure of the Atmosphere. Atmosphere composed of several layers.By caspar
1. 2. 3. 5. 4. Air Mass – LARGE parcel of air taking on characterictics of the area over which it forms. Source region - the area over which an air mass forms Air mass modification – when an air mass changes its characteristics. Arctic – A or Antarctic – AABy harken
Meteorology. Meteorology is the study of atmospheric phenomena. The word meteor means “high in the air”. The atmosphere is high in the air, isn’t it?. Types of meteors (what is in the atmosphere). Hydro meteors – “ water ” that is “high in the air” Ex: Clouds that hold waterBy erikawilliams

Air Mass. What is an Air Mass?. An air mass is vast pool of air Covers thousands of square kilometers Has the same humidity and temperature characteristics over its horizontal extent Air masses are classified based on the temperature and humidity at their source region.
Air Mass : An air mass is a huge body of air that has similar temperature, humidity, and air pressure at any given height. Air masses are classified by 2 characteristics Temperature Humidity
Air Mass Notes. Remember this… Air takes on the characteristics of the earth surface it is above. Air masses are classified by their: Temperature Origin. What does “c” stand for?. A. Crazy daisy Coastal Continental Cool. What does “m” stand for?. Macadamia Moon Pie
Air Mass Thunderstorms. We shall examine three phases of an air mass thunderstorm Cumulus Phase (Growth Phase) Mature Phase Dissipating Phase Life cycle can last from 45 minutes to over an hour. Air Mass Thunderstorms. Three Stages of Air Mass Thunderstorms. Cumulus Phase.
Air Mass Review. An air mass is a defined as a large body of air with very similar characteristics. Generally speaking, air masses are generally defined by temperature and humidity (moisture) Air masses are named based on the source region. Types of Air Masses.
Weather – Air Mass. extremely large body of air with similar characteristics of temperature and moisture. Forms when air stagnates for long periods of time over a uniform surface Characteristic weather of an air mass is determined by the surface above which it forms.
Daily Challenge, 9/15. Does air have mass? Consider the experiment we did yesterday. Write a paragraph answering the question above. Be sure to support your claim with evidence. What facts and observations from yesterday’s experiment show that your answer is correct?. Daily Challenge, 9/14.
Much cooler cP air mass over the northern midwest. mT air mass over NY. Normal cT air mass over desert. Summertime Air mass example. Soundings. Notice differences in surface T, T d , tropopause height and temperature. Also, APX has a frontal inversion separating the air masses. cP. mT.
