L.T. I can explain how air pressure changes the weather.
DO NOW:What are 3 things that effect weather?
HW: Pressure section 2 in workbooks (Follow Agenda!)
WIND!
Wind: the horizontal movement (compared with earth’s surface) of air in the atmosphere
Anemometer: a weather instrument used to measure wind speed
Wind Vane: an instrument that spins in the wind and points to the direction the wind is blowing from, which is the wind direction name
[ORIGIN from Greek anemos ‘wind’] [ORIGIN from Greek baros ‘weight’]
Follow Ms. Ware and tell me what her wind name would be?

In a high pressure area, air will (rise, sink) because the air is (less, more) dense.
This is because the air is (cold, warm)
and (rises, sinks). Therefore, clouds CANNOT form.
In a low pressure area, air will (rise, sink) because the air is (less, more) dense.
This is because the air is (cold, warm)
and (rises, sinks). Therefore, clouds are
LIKELY to form.
Correctly draw the direction of wind flow around both a high and a low pressure area
in the NORTHERN HEMISPHERE.
low pressure
high pressure
warm or cold air
air rising or sinking
clouds or no clouds
clockwise or
counterclockwise wind direction
winds toward or
away from the center
On the diagrams below, label which one represents a land breeze and which represents a sea breeze.
Correctly label on each diagram where the high and low pressure areas would be found.

How to convert pressure from millibars to inches…
USE YOUR CHART!!
Millibars (mb) = 1 mb per line
Inches (inches of mercury)= .01 inches
DO NOW: make sure this is in your notebooks!!!!!If you want to abbreviate millibars
Step 1: Drop the 9 or 10 in the frontStep 2: Get rid of the decimal
Ex. 1013.6 => 136or 998.4 => 984
If you want to change the abbreviation to the actual measurement
Step 1: If the number is lower than 500, add a 10 and replace the decimal
Step 2: If the number is higher than 500, add 9 and add the decimal
Ex. 348 => 1034.8978 => 997.8

Agenda:1.) Do Now: 5 minutes
2.) Review pressure/ fronts: 15 mins
3) Lab: 60 mins
What’s the relationship between wind and waves?
Using the chart on page 14, state the prevailing wind direction for each latitude below:
45°N
45°S
75°N
20°N
