Chapter 14: Weather and Climate (NATSC 003 Report)

Introduction : 
NATSC 003 Weather and Climate 2 Introduction Weather and Climate affects our Earth’s atmosphere. Different phenomena occurs with regards to them. Sometimes, weather and climate are classified as the same because it has referred to as a change in atmospheric condition. But, what is really a WEATHER and a CLIMATE?

Weather and Climate : 
NATSC 003 Weather and Climate 3 Weather and Climate Air Mass Cold, Warm and Occluded Fronts Stationary and Moving Fronts The Weatherman’s Tool Recording Weather A Storm Develops Formation and Movements of Storms Weather Causing Phenomena in the Philippines Types of Climate Climates in the Philippines

Air Mass : 
NATSC 003 Weather and Climate 4 Air Mass Air mass is the body of air that is carried by prevailing winds. It moves as a unit and it is really a body of air that moves. Air mass is large and extends for several kilometers. It’s homogeneous and it’s approximately the same amount of moisture.

Air Mass : 
NATSC 003 Weather and Climate 5 Air Mass Forms of Air Mass 1. Continental Air Mass 2. Maritime Air Mass 3. Polar Air Mass 4. Tropical Air Mass

Origin and Characteristics of Air Masses : 
NATSC 003 Weather and Climate 6 Origin and Characteristics of Air Masses

Air Masses Are Classified by Region : 
NATSC 003 Weather and Climate 7 Air Masses Are Classified by Region

Fronts : 
NATSC 003 Weather and Climate 8 Fronts Front is a boundary surface that separates air masses of different densities, one warmer and usually higher in moisture content than the other. It is also the boundary between a mass of warmer air and a mass of colder air.

Type of Fronts : 
NATSC 003 Weather and Climate 9 Type of Fronts 1. Cold Front -forms when a cold air mass pushes up a warm air mass ahead of it.

Formation of a Cold Front : 
NATSC 003 Weather and Climate 10 Formation of a Cold Front

Type of Fronts : 
NATSC 003 Weather and Climate 11 Type of Fronts 2. Warm Front -forms when warm air mass pushes cold air mass ahead of it.

Formation of a Warm Front : 
NATSC 003 Weather and Climate 12 Formation of a Warm Front

Type of Fronts : 
NATSC 003 Weather and Climate 13 Type of Fronts 3. Occluded Front -forms when a cold front overtakes a warm front and its able to lift the warm air mass.

Formation of an Occluded Front : 
NATSC 003 Weather and Climate 14 Formation of an Occluded Front

Stationary and Moving Fronts : 
NATSC 003 Weather and Climate 15 Stationary and Moving Fronts Stationary front occurs when the boundary between a cold air mass and a warm air mass is not moving. Moving fronts is already classified as the cold, warm, and occluded fronts.

The Weatherman’s Tools : 
NATSC 003 Weather and Climate 16 The Weatherman’s Tools The weatherman’s forecast is educated guesswork, based on the accurate observation obtained by man and machine. The weatherman, like any other professional, needs certain instruments to assist him in performing his work.

Basic Weather Instruments : 
NATSC 003 Weather and Climate 17 Basic Weather Instruments Temperature Atmospheric Pressure Wind Velocity Humidity Precipitation Clouds

Temperature : 
NATSC 003 Weather and Climate 18 Temperature 1. Thermometer -it measures the degree of hotness and coldness of a given substance.

Temperature : 
NATSC 003 Weather and Climate 19 Temperature 2. Thermograph -it records air temperature on graphing paper. It consists of a cylinder made to revolve once each week by means of clockworks inside.

Atmospheric Pressure : 
NATSC 003 Weather and Climate 20 Atmospheric Pressure 1. Mercury Barometer -made by filling a glass tube 32 in. long with a mercury and inverting it so that the open end of the tube is below the surface of mercury in a cistern.
