What do you need to make a cloud (three things). 1. Water vapor 2 What do you need to make a cloud (three things)? 1. Water vapor 2. Condensation nuclei 3. Air to cool to the dew point temp

Which layer of the atmosphere does the weather occur in? Troposphere

Why does water heat up and cool down more slowly than asphalt Why does water heat up and cool down more slowly than asphalt? Water has a higher specific heat

What percent of Sun light does the atmosphere absorb and/or reflect

What is convection? The Transfer of heat through a fluid (gas or liquid)

What is conduction? The transfer of heat through a solid

What is radiation? The transfer of energy such as electromagnetic that can travel through various mediums (liquids, gasses) or space.

What type of air rises? Warm air

What do we call the temperature at which air becomes saturated What do we call the temperature at which air becomes saturated? Dew point

What do we call the height at which clouds form What do we call the height at which clouds form? Lifted condensation level (LCL)

What is relative humidity (think of the fish tank example) What is relative humidity (think of the fish tank example)? The amount of moisture in the air compared to the amount of moisture that the air could hold

What is humidity? The amount of water vapor in the air.

What causes wind? A difference of pressure.

How does air in a low air pressure system flow How does air in a low air pressure system flow? Counter clockwise, in and up.

How does air in a high air pressure system flow How does air in a high air pressure system flow? Down, out and clockwise.

How can you have a day without clouds How can you have a day without clouds? High pressure when air is sinking, it warms up, and does not reach the dew point.

What is latent heat? The energy that is stored in the air until condensation occurs.

What is a temperature inversion What is a temperature inversion? An increase in temperature with height in an atmospheric layer.

What does nimbus mean? That it is precipitating

Describe the water cycle?

What is ozone made of? Three oxygen molecules O3

What is the function of the ozone layer What is the function of the ozone layer? It absorbs harmful UV rays that can cause cancer.

What is heat? Is the transfer of energy that occurs because of a difference in temperature.

What is temperature? A measurement of how rapidly or slowly molecules move around.

What are the three temperature scales and what are they based on What are the three temperature scales and what are they based on? Fahrenheit: Old English system Celsius: Based on the freezing and boiling points of water. Kelvin: Based on Absolute zero being zero on this scale.

What is -40 F converted to in C ? -40 C

What is the boiling point of water in F and in C ? 212 F and 100 C

What is the temperature of absolute zero on the Kelvin scale? 0 degrees

Describe how to use the LCL chart Describe how to use the LCL chart? Find where the Dry bulb and Dew point temperature lines meet, look over to the Y axis and that is the latitude of the clouds.

What is coalescence. One way that cloud droplets can increase in size What is coalescence? One way that cloud droplets can increase in size. When cloud droplets collide they get larger. As these larger droplets fall they collide with other droplets. When the droplets are too large to stay suspended in the cloud they fall and it rains.

What is evaporation? The phase change from a liquid to a gas.

Describe orographic-lifting Describe orographic-lifting? When an air mass is forced up a mountain, it cools, reaches the dew point temperature and forms clouds and often rains.

When is air considered to be unstable? When it rises.

Why does stormy weather create low pressure Why does stormy weather create low pressure? Water vapor weighs less than the dry nitrogen that it is replacing.

Why does air pressure decrease as you increase in altitude Why does air pressure decrease as you increase in altitude? There is less air on top of you, therefore less weight or pressure.

The atmosphere is composed of which two main gases and by what percent The atmosphere is composed of which two main gases and by what percent? Nitrogen 78% Oxygen 21%

What is the main green house gas? Carbon dioxide or CO2

What gas do you breath out? Carbon dioxide or CO2

What is the scientific term for “dust and stuff” in the atmosphere What is the scientific term for “dust and stuff” in the atmosphere? Condensation Nuclei

What is the real name for the “weather sphere”? Troposphere

What is the source of all NRG that reaches the Earth? Sun

What is the amount of solar NRG that the Earth’s surface absorbs? 50%

What is the relative humidity if the air is fully saturated? 100%

What does condensation nuclei provide for water droplets What does condensation nuclei provide for water droplets? A surface area to cling to.

What is the name of the stored energy that is not available until condensation occurs? Latent heat
