Understanding Weather

Condensation Nuclei

• Microscopic particles in the atmosphere that absorb water vapor.

• Any microscopic particles in the atmosphere on to which water vapor condenses.

• Large droplets of water that fall from clouds.

• Particles that prevent condensation from occurring.

Condensation

• A chemical reaction where water vapor turns into gas.

• A physical process in which water vapor becomes a liquid.

• The process of water evaporating into the atmosphere.

• A method of purifying water through boiling.

Climate

• The expected weather in an area at a point in time, which considers the seasonal changes.

• The average temperature of a region over a year.

• The daily weather conditions in a specific location.

• The long-term patterns of temperature and precipitation in an area.

Heat Index

• A temperature measurement that only considers the temperature.

• A temperature measurement that only considers humidity.

• A temperature measurement which considers both the temperature and the humidity and represents what the atmosphere 'feels-like'.

• A temperature measurement that indicates the temperature at which water boils.

Cumulus

• Fluffy, white clouds that often indicate fair weather.

• Dark, stormy clouds that bring heavy rain.

• Thin, wispy clouds found at high altitudes.

• White, billowy, low-level clouds with a flat base.

Deposition (Sublimation)

• The process in which water vapor skips the liquid state directly to a crystal state on a surface.

• The process of converting a solid directly into a gas without passing through the liquid state.

• The process of water vapor condensing into liquid water droplets.

• The process of freezing water into ice at low temperatures.

Stratus

• Low-level clouds that form a flat or large sheets, gray layer of heavy clouds not far from the ground.

• High-altitude clouds that appear wispy and thin.

• Cumulus clouds that are fluffy and white, indicating fair weather.

• Thunderstorm clouds that are dark and towering.

Weather

• The actual conditions of the atmosphere at a particular time and place.

• The long-term average of atmospheric conditions in a region.

• The study of atmospheric phenomena and their effects.

• The measurement of temperature and humidity in the air.

Dew

• Formation when water vapor in the air touches the cooler ground.

• A type of precipitation that occurs during winter.

• Water droplets that form on leaves during the day.

• A cloud formation that indicates rain is coming.

Evaporation

• Physical process by which liquid turns directly to water vapor below the boiling point.

• Chemical reaction that occurs when a liquid is heated to its boiling point.

• Process of converting water vapor back into liquid water.

• Physical change that involves the freezing of a liquid.
