Atmosphere & Air Temperature
this is most likely the result in NC when the wind changes direction ... from blowing from the north to blowing from the south
What is an increase in temperature?
this process occurs when the sun warms water
What is evaporation?
this most likely causes the grass in an area to be wet in the morning even when there was no precipitation over night
What is condensation? The air cooled above ground during the night and water vapor condensed on the grass
the instrument is the best one to use to predict weather changes
What is a barometer?
this explains why storms that are in the western United States may affect an area in eastern US a few days later
What is the jet stream winds blowing from west to east?
the best description of weather conditions in an area that has mostly cirrus clouds
What is fair weather?
The type of weather most often produced by a low pressure system
What is rainy weather?
The best explanation for why there are high precipitation levels near the equator
What are warmer climates? Warmer climates create evaporation and increased evaporation leads to more precipitation.
this is mostly responsible for moderating weather conditions along the coast of North Carolina
What is the Gulf Stream?
this best describes the cause of day to day weather changes
What are moving air masses?
the weather condition that will most likely happen on a hot summer day when cumulus clouds grow taller and darker
What is a thunderstorm?
this is most likely to rise or increase when there is rainfall during the summer season in North Carolina
What is humidity?
this is the cause of rising surface temperatures in the Pacific Ocean, drought in western US, AND flooding on the Pacific Coast of South America
What is El Nino?
this weather condition will mostly occur when air pressure falls and temperatures are near 32 degrees F
What is a snowstorm?
the weather condition that might form with warm, moist air rising over warm areas of the ocean
What is a hurricane?
this happens to the temperatures in NC when a warm air mass replaces a cold air mass
What is rising temperatures?
these two weather conditions affect the humidity in North Carolina
What are temperature and precipitation?
this cloud formation usually occurs when there is lightning and thunderstorms
What is cumulonimbus?
the weather condition that will most likely occur the day before a high pressure system moves into the area
What are clear skies?
The effect a tornado has on normal wind speed and direction
What is a tornado increases in wind speed and may change the direction?
the reason why winds at the beach change direction between day and night
What is the temperatures over land and over water change?
this is why scientists collect data about the amount of water vapor in the air
What is to help determine humidity?
this type of cloud is called fog when it is near the ground
What are stratus clouds?
this has the greatest effect on wind speed
What is air pressure?
the type of weather expected when the air pressure has been increasing over the last few days
What are increasingly clear skies and dry weather?
