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

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.

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
![Page 20: 2/28 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.](https://reader034.fdocuments.net/reader034/viewer/2022051517/56649ef35503460f94c0571c/html5/thumbnails/20.jpg)
![Page 21: 2/28 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.](https://reader034.fdocuments.net/reader034/viewer/2022051517/56649ef35503460f94c0571c/html5/thumbnails/21.jpg)
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
