  • The area where 2 air masses meet

  • 4 kinds of fronts

    • Warm front

    • Cold front

    • Stationary front

    • Occluded front

  • Each front has a symbol

  • Side of the line the symbols are on indicate direction of movement


What does each front mean

What does each front mean?

  • Warm front – warm air is replacing cold air

  • Cold front – cold air is replacing warm air

  • Stationary front – air masses are not moving due to similar pressures

  • Occluded front – warm air is pushed up due to cold air moving in from both directions

    front animation


What happens when cold and warm air meet

What happens when cold and warm air meet?

  • Cold air sinks and warm air rises

  • Warm air carries moisture

  • Moisture condenses

  • Clouds form

  • Once air is saturated with moisture, precipitation in some form occurs


What happens before and after a warm front

What happens before and after a warm front?

Before

After

Warm and more humid

Clearing clouds

Rising barometer

Temp and dew point are close

  • Cool or cold temps

  • Falling barometer

  • Increasing, thickening clouds

  • Light to moderate precipitation

  • Temp and dew point get closer together


What is dewpoint

What is dewpoint?

  • The temperature at which air is saturated enough for water to condense

  • High dewpoint – temperature and dewpoint are close together

  • Low dewpoint – temperature and dewpoint are far apart

  • ALWAYS a dewpoint


What happens before and after cold fronts

What happens before and after cold fronts?

Before

After

Lower temps

Rising pressure

Showers then clearing skies

Temp and dewpoint get further apart

  • Warm

  • Falling barometer

  • Increasing clouds

  • Short period of precipitation

  • Temp and dew point close together


What to expect from a stationary front

jet stream


Assignment4

Assignment!

  • Predicting weather

  • Edheads weather prediction

  • We’ll do this as a group


Assignment5

Assignment!

  • Complete the forecasting weather map worksheet

  • Put in the box when you are finished


Clouds

Clouds

How they form and what they mean


What happens as water evaporates

What happens as water evaporates?

  • Humidity – the amount of water in the air

  • Amount of water vapor increases = higher humidity

  • Air pressure increases as amount of water vapor increases

  • Air is saturated when water entering air = water returning to surface

  • Warm air contains more vapor than cold air


How is humidity measured

How is humidity measured?

  • Using a hygrometer

  • Relative humidity – ratio of actual amount of water in the air compared to the amount of water air can hold at that temperature and pressure

  • If amount of water vapor is constant, what will happen to the humidity if you raise the temperature? Lower it?


So how do clouds form

So how do clouds form?

  • Temperature can change without heat input or loss

  • These changes are called adiabatic temperature changes

  • Happens when air is compressed or expanded

    • Expansion cools

    • Compression warms


What happens to air and vapor as it rises

What happens to air and vapor as it rises?

  • Overall, air resists lifting

  • 4 factors make air light enough to be lifted

    • Oographic lifting

    • Frontal wedging

    • Convergence

    • Localized convective lifting


What is oographic lifting

What is oographic lifting?

  • Elevated terrain blocks air from moving forcing it to go up and over

  • Causes the rainshadow effect

    • Wettest places on the windward side of mountain

      • Lifting air reaches dew point and condenses  clouds form  air is pushed higher and forced to release moisture as precipitation

      • By the time air gets to the other side of the mountain the moisture has mostly been lost


What is frontal wedging

What is frontal wedging?

  • Air masses collide in flatter areas

  • Area between two air masses is a front

  • Cooler air sinks and warmer air rises  condenses  forms clouds


Brief review1

Brief Review

  • What is a front?

  • What are the 4 different types of fronts?

  • Draw each front as it appears on a weather map.

  • How does weather change as each front moves through?


What is convergence

What is convergence?

  • Air in lower atmosphere collides together and is forced upward

  • Air converging from 2 different directions must go somewhere, down is not an option

  • Example

    • Ocean winds blow toward the shore

    • In Florida, this happens on both sides of the state so air flows together

    • Produces many afternoon storms


What is localized convective lifting

What is localized convective lifting?

  • Due to unequal heating of Earth’s surface

    • Causes pockets of air to be warmer than surrounding air

      • Example: parking lots

  • Warm air will rise creating thermals

    • Birds and hang-gliders use these to glide higher with less energy

  • Warm air rises  reaches dewpoint  clouds form

  • Normally with flat base in domes or towers

  • middle clouds

  • 2 other types of middle clouds

    • Alto – prefix meaning middle

    • Altocumulus – rounded masses that are larger and more dense than cirrocumulus

    • Altonimbus – uniform white – greyish sheet, sun or moon visible as a bright spot

      • Often snow or rain accompany these


What are stratus clouds

What are stratus clouds?

  • Low clouds

Do clouds ever touch the ground

Do clouds ever touch the ground?

  • Fog is a cloud with its base on or near the ground

  • No physical difference with any other cloud

    • Difference is in placement and formation

    • Usually the result of warm air moving over a cooled surface

    • Can form when cool air moves over warm water – steamy appearance

    • Forms when enough water vapor brings about saturation


How does precipitation form in cold clouds

How does precipitation form in cold clouds?

  • Supercooling and supersaturation – Bergeron process

  • Cloud droplets do not freeze at 0°C, instead it must be about -40°C - supercooled

    • Freezing nuclei cause water droplets to freeze

  • Greater than 100% humidity – supersaturated

    • Ice and water cannot exist together in clouds

    • Evaporating water quickly produces snowflakes or ice


How does precipitation form in warm clouds

How does precipitation form in warm clouds?

  • Rainfall in clouds is well below freezing – even in tropics

  • Collision – coalescence process – water absorbing particles remove moisture forming large droplets

    • Drops collide and mix with smaller slower droplets


Does ice form in warm clouds

Does ice form in warm clouds?

  • Hail

    • Forms in cumulonimbus clouds

How do sunspots cause climate change

How do sunspots cause climate change?

  • Controversial

  • Sunspots are dark spots on the surface of the sun

  • Increase in sunspots correlates to an increase in temperature and vise versa

  • Spots are cooler spots in the sun and area around them warms to make up for the difference

  • Less spots = more solar wind = more clouds = less sun hitting Earth

What about la ni a

What about La Niña?

  • Opposite of El Niño

  • Caused by cooler surface temperatures


What are the results of el ni o

What are the results of El Niño?

  • Wet winters in southeast US

  • Droughts in Indonesia and Australia
