Meteorology 1

Can be defined simply as a study of weather. It is the branch of science that studies the physical, dynamic, and chemical properties of the atmosphere. with a focus on weather forecast: the condition, development, and changes of the weather.

Meteorology

Meteor

High up or Higher Things

Logos

Study

Mixture of gasses that surrounds the earth.

Atmosphere

Atmos

Vapor or Steam

Spharia

Sphere or Globe

State of the Atmosphere at a given place and time.

Weather

What is ISA?

International Standard Atmosphere

A measure of hotness and coldness expressed in terms of any of several scales, including Fahrenheit and Celsius.

Temperature

Weight of Air above a given area on Earth's Surface.

Pressure

Amount of water vapor ( gas) present in the air.

Moisture

Measurement of the speed at which air moves horizontally.

Wind Velocity

The greatest distance one can see and identify objects.

Visibility

Hypothetical Standard Atmosphere defined by ICAO.

ISA

What is MSL?

Mean Sea Level

What is MSL Temperature?

15 degree Celsius / 59 degree Fahrenheit

3 Types of Lapse Rate

Pressure Lapse Rate

Temperature Lapse Rate

Air Density

What is Pressure Lapse Rate standard formula.

-1 in Hg / 1000 feet

What is Temperature Lapse Rate standard formula.

-2 degree Celsius / 1,000 feet

What is the standard Air Density?

1225 g/ m2 (squared)

Convert Fahrenheit to Celsius formula. C =

C = ( F - 32) x 5 / 9

Convert Celsius to Farenheit formula.

F = ( C x 9 / 5 ) + 32

Air movement is caused by the uneven heating of the Earth's Surface. This unequal heating also changes the pressure in different places and creates pressure systems identified by the isobars.

Atmospheric Circulation

An imaginary line that connects points with equal Pressure.

Isobar

The _ is measured by the instrument called barometer which mainly consists of two types. Mercury and Barometer.

Atmospheric pressure

2 instruments that measure Atmospheric Pressure.

Mercury

Barometer

5 Layers of the Atmosphere.

Troposphere

Mesosphere

Stratosphere

Thermosphere

Exosphere

Higher Density

Sinks

Lower Density

Floats

2 types of Barometer

Mercurial

Anneroid

What is Mercurial?

Measures pressure

What is Anneroid?

Measures altitude using pressure

A _ is an area of the Earth's Atmosphere that has a particularly high or low pressure compared to the surrounding air.

Pressure System

Pressure Systems has 5 surrounding types of air:

High

Low

Ridge ( for High Pressure )

Trough ( for low pressure )

Col ( Neutral )

Are created by the temperature and pressure differential.

Local Wind Patterns

Horizontal motion of air that blows from an area of high pressure to an area of low pressure.

Wind

5 Local wind patterns.

Sea Breeze ( Cold air coming from the sea )

Land Breeze ( Cold air coming from the Land )

Valley Breeze ( Cold air coming from the Valley )

Mountain Breeze ( Cold air coming from the Mountain )

Katabatic Winds ( Any down sloping wind )

Defined as its resistance to rising vertical motion.

Atmospheric Stability

Visible state of water vapor as a result of condensation.

Clouds

2 Types of Clouds.

Shape and Height

4 types of shape clouds.

Stratus

Cumulus

Cirrus

Nimbus ( when it rains )

4 types of Height Clouds

Low Clouds ( starting with " Stra " )

Middle Clouds ( starting with " Alto " )

High Clouds

Clouds with vertical movements

Any form of particle, whether solid or liquid, that falls from the atmosphere.

Precipitation

7 types of Precipitation

Rain

Rain shower

Drizzle

Freezing drizzle

Ice pellets ( Sleet )

Hail

Snow

A Large body of air with uniform temperature and moisture content. When an moves, it collides with other with different characteristics, creating Fronts.

Airmass

Boundaries between Air masses in which weather phenomena occur.

Fronts

3 Types of Fronts.

Cold Front

Warm Front

Stationary Front
