Realms of hotness and coldness

Connectors. How to understand the event and explain clearly explain it and its effects.

Weather, as well as, how to describe it.

Temperature

Basic Explanation

Temperature is defined as: "The degree of hotness or

coldness of a body or environment"

Temperature gives us a way to express our hotness or

coldness in terms of numbers instead of subjective terms

(cold or hot). Thus, temperature is commonly used in

the realm of weather.

How does temperature vary during the day?

Why does the temperature vary?

Temperature has a minimum in the morning hours and has a

maximum in the early evening. This of course is based on

the amount of sun that a given area receives during the day.

During daytime hours the sun is shining and the

temperature increases. But after the sun sets the

temperature slowly starts to lower until the sun rises the

next day. The magnitude of the highest and lowest

temperature is based on the time of year. In the summer,

high temperatures occur and in the winter low

temperatures occur.

Dew point temperature is defined as:

"the temperature at which dew begins to form."

Therefore, dew is formed due to the temperature reaching dew point.

How it is Measured It is simply the temperature when dew forms. So weather stations have a device that captures air and holds it in. It then decreases the temperatures, consequently, dew forms on its sensor mirror. When that happens it records the temperature and that is the dew point temperature.

What temperature is decreased?

A more common way to measure dew point is to actually measure Relative Humidity (Rh) through mathematical equations.

Some things to know about dew point: The current dew point will never be higher then the current temperature. If the temperature is at the dew point and the temperature falls, the dew point must follow. Higher the dew point temperature more moisture that is in the air. Example: Death Valley(desert) California has low dew points, thus it feels dry. Key West Fl. has high dew points, thus it feels humid and sticky.

For the hail embryos to grow, they must remain in a layer of super-cooled water for a length of time -- the longer the residency, the larger the hailstone's potential size

Hail To form hailstones the size of golf balls requires over ten billion super-cooled droplets.

Gale

a strong current of air from 32 to 63 miles per hour (about 51 to 102 kilometers per hour)

Thunderstorm a form of weather characterized by the presence of lightning and its acoustic effect on the Earth's atmosphere known as thunder.

Does lightening cause thunder?

Thunder occurs as a result of the acoustic effect of lighting on the Earths atmosphere.

Four Main Types of Fog

Whats heavier, cold or warm air?

What is dense?

What happens when air rises?

How is it similar to a cold front?

How is it different?

What are some differences in the rains these fronts produce?

fog

Clouds that form at ground level (with in 50 ft of the surface). The processes forming it, however, are usually different from those that form clouds.

The scene is a thick foggy airport ramp, with ATC tower in the background. Describe the scene above.

steam or evaporation fog.-

When a cool air mass moves over a relatively

warm water body or land mass. So the warm

heat air from the water body meets that cold

air mass and causes the water to condense,

thus forming steam fog.

advection fog

So what you have is a warm moist air front

thats moving. It comes in contact with a cool

current of water. This cool current cools down

the air, and its possible that the contact point

cools down the air enough that it get to the

temperature at which it is gong to condense.

advection fog (cont.)

So because it isnt dependant on the time of

dayadvection fog can stick around for a very long

period of time. This is why places like London and

San Fsco. can get fogged in for extended periods of

time, due to the advection fog.

upslope fog

When a warm moist air mass gets pushed

up a mountain or hill as it gets pulled, the

air cools and condenses. Commonly found

at mountain peaks.

ASSIGNMENT How does sunshine help clear

fog?

Clouds are water vapor. Water vapor is tiny droplets of water floating around in the air. Water evaporates;

especially when exposed to heat.

Because water evaporates; especially when exposed to heat, sun does help clear fog.

Tornado

a violent destructive whirling wind accompanied by a funnel-shaped cloud that progresses in a narrow path over the land.

St. Louis Airport tornado

Tornadoes form in thunder clouds, where strong

updrafts of air come close to an unusually strong

downdraft.

This tends to happen during most violent storms; often

at cold fronts, where warm air is forced to rise quickly.

The strong updrafts leave a low pressure area in the

cloud. Air rushes into replace the updrafts and evens

out the pressure.

Because the updrafts are so strong, and the incoming

air is warmer air from below, updrafts gain even more

strength. As it streams in and up, this air twists the

already soaring air into a spinning spiral.

the act or sport of flying a heavier-than-air craft without power by utilizing ascending air currents

How much time can a tornado warning give you?

Tornado watches are issued from 12 hours down to a couple of hours in advance.

Pronunciation: my-crow-burst Also Known As: downburst Examples: A downburst is defined as a strong downdraft with an outrush of damaging winds on or near the ground. If the swath is less than 2.5 miles, it is called a microburst. Microbursts are quick-hitting events and are extremely dangerous to aviation. Microbursts are sub-classified as dry or wet microbursts, depending on how much rain accompanies the microburst when it reaches the ground. http://www.youtube.com/watch?v=0uD_eeKsrc4

Hurricane

a storm system characterized by a low-pressure center and numerous thunderstorms that produce strong winds and heavy rain

Spiral bands of a hurricane are where the

action is. Embedded within these bands

is the heaviest rain, strongest winds,

continuous lightning and possible

tornados. Between the bands, the

conditions are less severe.

A hurricane does not represent very strong

continuous winds and heavy rain.

It is impossible for you to know when the

storm is definitely passed.

These two are begging for a connector!
