Climate and weather
Air masses (definition and how they move - warm air vs cold air)
Large body of air with similar temprature and humidity characteristics. Caused by uneven heating of the earth.
movement of air masses creates water
Air moves from higher pressures to lower pressures.
Differences between weather and climate
Climate is the average pattern of the weather for a particular place,
whilst weather is the state of the atmosphere at a particular place and time as regards heat, cloudiness, dryness, sunshine, wind, rain, etc
Weather can change in a short period of time whilst climate takes a long time.
Air Fronts (cold and warm only, including what weather is created)
A boundry between air masses of different tempratures.
Weather is created from air masses replacing each other.
Reading a weather map
Meteorologists are people who study the atmosphere in order to predict the weather, they use weather maps to help them predict the weather. They predict weather by looking at fronts. Fronts are the areas of different temperature.People can see that if a warm front is coming from the west and a cold one from the east so that it would clash and create weather. With this you can measure how long, how bad, how much the weather will be.

Similarities between Weather and Climate
Weather and climate both measure temperature in a specific region. They also measure humidity, precipitation, cloudiness, brightness, visibility, wind, high and low pressure.
Weather
Factors
temperature, humidity, precipitation, cloud cover, wind speed, direction, air pressure
Air pressure (number of molecules, temperature and altitude.)
Air pressure is basically how much molecules of air there is in an area. Places with low pressure have little molecules and places with high pressure have high amounts of molecules. High temperature = high pressure and low temperature = low pressure. Also high altitude has low pressure because there is a smaller amount of air above it and low altitude = high pressure because it has a higher "ocean" of air.
