Study Notes
Weather and Climate
- A portion of the United States experiencing days of constant weather is called air-mass weather.
- An air mass that forms over the Gulf of Mexico is a mT (maritime tropical) air mass.
- Air masses that have the greatest influence on weather in the midwestern United States are mT and cT air masses.
- Lake-effect snow is associated with a mP air mass.
- A warm front is often characterized by long periods of light rain.
Weather Fronts
- A cold front often produces severe storms, thunderstorms, and rain.
- There are four types of fronts: warm, cold, occluded, and stationary.
- A warm front brings warm air, a cold front brings cold air, an occluded front brings cold air and rain, and a stationary front brings little change.
Hurricanes
- When a hurricane reaches land, its intensity decreases due to friction and the lack of warm, moist air.
- The eye of a hurricane is characterized by calm weather, with no heavy precipitation.
- The eye of a hurricane does not have the greatest wind speeds.
Air Masses
- There are four types of air masses: maritime polar (mP), maritime tropical (mT), continental polar (cP), and continental tropical (cT).
- mP air masses are cold and moist, mT air masses are warm and moist, cP air masses are cold and dry, and cT air masses are warm and dry.
Climate
- Climates at high latitudes are not very warm, and nearby lakes can cause a climate to be colder.
- Vegetation can increase the amount of precipitation that falls over an area.
- Places at lower elevations generally have higher temperatures.
- Humid tropical climates typically experience warm temperatures, but not severe winters or low humidity.
- In a dry climate, yearly precipitation is less than the potential rate of evaporation.
Global Climate Change
- The greenhouse effect is a natural warming effect of the earth and its atmosphere.
- Recent global climate change appears to be the result of increases in greenhouse gases in the air.
- Melting ice caps can result in a rise in sea level, and an increase in ocean temperatures can cause melting of sea ice.
- There are three major climate zones: tropical, temperate, and polar, with differing temperatures due to latitude and altitude.
Human Impact
- Humans have contributed to the increase in the levels of carbon dioxide in the atmosphere, leading to global warming.
- Global warming can affect global precipitation, and cities are referred to as urban heat islands due to factors such as vegetation and pavement.
Thought Questions
- Hurricanes and tornadoes have different formations, and it is more likely to encounter tornadoes in St. Louis, but hurricanes in Florida.
- To reduce the steady increase in global carbon dioxide levels, efforts such as reducing fossil fuel consumption, increasing renewable energy, and promoting sustainable practices can be taken.
