Weather Variables

Sentences based on Mind Map of Weather

Water Cycle:

• More heat energy evaporates liquid water into water vapor and increases the relative humidity.
• Less heat energy condenses water vapor into liquid water and reduces the relative humidity.
• Less heat energy from the Sun lowers the temperature and condenses water vapor into liquid water.
• More heat energy from the Sun increases the temperature and evaporates liquid water into water vapor.
• Condensed water vapor into liquid produces precipitation.

Precipitation:

• Precipitation that forms from condensed water vapor into liquid water above 32 degrees F (0 degrees C) will be a liquid (rain).
• Precipitation that forms from condensed water vapor into liquid water equal to or below 32 degrees F (0 degrees C) will be a solid (ice-snow-hail).

Cloud Cover:

• High relative humidity produces large clouds.
• Low relative humidity produces small clouds.

Wind:

• Less heat energy from the Sun causes cold air to sink.
• More heat energy from the Sun causes warm air to rise.
• Air masses that meet with no temperature difference produce no wind.
• Air masses that meet with some temperature difference produce light winds.
• Air masses that meet with large temperature difference produce strong winds.

Extras based on Air Pressure (weight of Air pressing down)

• Warm air rises and produces low air pressure that evaporates liquid water into water vapor.
• Cold air sinks and produces high air pressure that condenses water vapor into liquid water.
