1.What are the units for temperature, air pressure and wind? 2.How are winds named? 3.What is a station model diagram? Journal #9: Weather Measurements
Weather Measurements Objective: Understanding how weather is measured and summarized on a station model diagram.
Station Model Model used by scientists to summarize the weather for a certain location at a certain time Weather Measurements
Wind Stick Stick used to represent the direction of wind POINTS IN THE DIRECTION WIND IS COMING FROM Weather Measurements
Wind Speed Measured in km/hour or in knots Represented by feathers Whole feather = 10 knots Half feather = 5 knots Weather Measurements
Cloud Cover Percentage of cloud cover indicated by the portion of the circle that is darkened Weather Measurements
Present Weather Indicated by a symbol on the left side of the station model Weather Measurements
Visibility How far ahead you can actually see, in miles Weather Measurements
Temperature Upper left corner of the station model Degrees Fahrenheit Weather Measurements
Dew Point Temperature Lower left corner of the station model Degrees Fahrenheit Weather Measurements
Precipitation Lower right hand corner of the station model Amount of precipitation in the last 6 hours Weather Measurements
Barometric Pressure Written in short hand on a station model RULES: Take a look at the first number in the pressure If it is bigger than 5, put a 9 in front of the number If it is smaller than 5, put a 10 in front of the number Move the decimal point one place to the left (millibars) Weather Measurements
