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.

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
