METO 1010 Online Lab 9. Atmospheric Pressure and Winds 1 Instructions: 1) Type your answers in this Microsoft Word file and save your completed lab on your computer. Do not modify the format of the file. 2) Upload your lab on CANVAS by the due date. To upload the file, go to the course homepage and click on “assignments”. Click on the assignment that you want to submit, and on “submit assignment”. In the “file upload” box, click on “choose file” and select the appropriate file. Finally, click on “submit assignment”. Only .doc, .docx, and .pdf files are accepted. 3) In questions that require calculations, you are not required to show every step of your work, but the more detailed your answers are the more likely you are to receive partial credit for wrong answers. 4) Proper units and terminology are always necessary. 1) Using the values for the average atmospheric pressure at sea level, perform the following pressure conversions. Keep to decimal figures. (5 points) a) 500 mb=_____ 14.76 _____ in Hg b) 30 in Hg=_____ 1015.96 _____ mb c) 30 in Hg=____ 762.03 ______ mm Hg d) 700 mm Hg=_____ 27.56 _____ in Hg e) 40 mb=____ 4000 ______ Pa 2) Go to the following website https://forecast.weather.gov/MapClick.php?lat=40.2337&lon=- 111.6685#.W-XBgpNKhPZ . Report the value for the current atmospheric pressure at the Provo Airport. (0.5 point) Atmospheric Pressure at Provo Airport (in Hg)= 30 in Hg 1
(I swear this is what it was!) 3) Convert into mm Hg and report the value below. Keep two decimal figures. (1 point) Atmospheric Pressure at Provo Airport (mm Hg)= 762.03 mm Hg 4) Convert into mb and report the value below. Keep two decimal figures. (1 point) Atmospheric Pressure at Provo Airport (mb)= 1015.96 mb 5) Convert into bars and report the value below. Keep five decimal figures. (1 point) Atmospheric Pressure at Provo Airport (bars)= 1.01596 bars 6) Convert into Pa and report the value below. Do not report any decimal figure in your final result. (1 point) Atmospheric Pressure at Provo Airport (Pa)= 101,596 Pa 7) On a given day, you measure with your barometer an atmospheric pressure in Orem of 850 mb. You want to construct a sea-level map. What pressure do you report for Orem? Use a rate of change in pressure vs. elevation of 100 mb/km. The elevation of Orem is 1445 m. (1 point) 994.5 mb 8) Fill out the table below. Write the three-digit coded form for each pressure value given in the “decoded pressure” column. Then write the decoded form for each coded pressure. Units are a must . (6 points) Decoded pressure Coded pressure Coded pressure Decoded pressure 2
