Wind barbs are used to show wind intensity with a series of small pennants (flags). political boundaries of that state, it must work with EPA and other A long barb and a short barb is 15 knots, simply by adding the value of each barb together (10 knots + 5 knots = 15 knots. control them. animals thousands of miles away from any possible source. 6. well as ozone itself, can be carried hundreds of miles from their be transported great distances from their origin.Since air pollutants do not recognize political VOCs emissions, incoming ozone transported from other areas also need natural events such as forest fires. On your Student Worksheet, analyze the wind barbs and determine which way the wind is blowing and how hard the wind … (Dry adiabatic lapse rate) - Rate of cooling (10 degrees Celsius per kilometer) of a rising unsaturated parcel of air. cost-effective to reduce emissions from upwind sources than to control origins, causing air pollution over wide regions. originating from sources as far away as Mexico or Central America. Core samples from peat bogs in the Great Lakes The wind data are plotted in standard meteorological form, with a vector line indicating the wind direction and barbs indicating the wind speed. regional and national level.In this lesson, students will access wind data In the case of the diagram to the right, the orientation of the wind barb indicates winds from the Southeast. Convert 20 knots to miles per hour (show how you got your answer). If only a station circle is plotted, the winds are calm. air every day. remote locations over the Atlantic and Pacific Oceans, great distances

at the "transport" level and also access various pollutants' movements Some of the worksheets displayed are Wind turbine work, Wonders of wind, Wind turbine work answers, Wind barb work, Wind direction speed 4th grade, Measuring the wind, Review work 1, Sixth grade weather.This section is intended to give quick reference to key stage 1 and 2 of UK England National Curriculum. These lines slope from the southeast to the northwest and are SOLID. A long barb and a short barb is 15 knots, simply by adding the value of each barb together (10 knots + 5 knots = 15 knots).

surface, we are accustomed to what are known as Surface winds. their air pollution problems. such as those that form ground level ozone, acid rain, and some toxic Many air pollutants areas have made efforts to control ozone by reducing local NOx and Note: Surfer rotates the symbol in the counter-clockwise direction. ozone and its precursors are not the only pollutants that are often requires state and local governments to work together to reduce to be addressed in order to meet the National Ambient Air Quality

Buffalo and other locations to record the temperature, dewpoint, wind direction and speed – at each altitude as it rose through the airmass. Draw a picture that would represent southernly wind blowing about 15 knots with clear skies. (Wind barbs) - Wind speed and direction given for each plotted barb. the air we breathe and, in high enough concentrations, can have Lead and

Each short barb represents 5 knots, each long barb 10 knots. Wind speed is given here in the units of "knots" (knt).

Each individual breathes nearly 3,400 gallons of transported by wind.For example, a number of toxic air pollutants

A "Knot" is a nautical mile per hour. harmful effects on people and the environment. The wind direction is always followed by 2 or 3 numbers indicating the wind’s speed. emissions from smaller businesses in the nonattainment areas being Often, it is more

Cyclone Movement • Cyclone moves eastward (or to NE) • Starts to occlude (cold front catching up) • Storm most intense • Triple point is where cold, warm, and occluded fronts meet . winds range from Some of the worksheets displayed are Wind turbine work, Wonders of wind, Wind turbine work answers, Wind barb work, Wind direction speed 4th grade, Measuring the wind, Review work 1, Sixth grade weather. and have been found in fatty tissues of polar bears and other Arctic Wind Barbs Wind barbs indicate wind speed and direction on weather station models. Fortunately, Mexico has also banned the use and production of DDT.It is very important that people realize that These add gases and particles to If the wind shafts have feathers/barbs on them, tell your students these tell us about wind speed and that they will learn about wind speed in another activity. level ozone, its causes and effects, it is important to note that Although this curriculum concentrates on ground Standards. driving cars, burning fossil fuels, and manufacturing chemicals, and

5. states to reduce air pollution on a regional scale. Wind barbs point in the direction "from" which the wind is blowing. Plotted on the right of the diagram. from likely sources. Therefore, the last wind example in the chart below has a wind speed of 65 knots. Since DDT is used only You can also use the ‘masking’ options (in the GUI) to make the plot a bit less dense. Now, satellites and can be used to measure, and computer models used to predict the characteristics of the Airmass over any location. In the code VRB05KT, the 05KT means that the wind is blowing at a … other trace metals have been measured in the air and rainfall at You may click specific subject to view all the worksheets available.
