Question

Using a pencil on your printout, follow the steps below to complete the pressure analysis for the map area to determine the pressure pattern that existed at the time the observations were made. For completing the map, refer to the Tips on Drawing Isobars in the first portion of Investigation 1A from the Investigations Manual. More than one isobar of the same value may need to be drawn on the map if pressure values located in separate sections of the map area require it. Consider each pressure value to be located at the center of the reported number. Isobars with values of 1016 and 1012 mb have already been drawn on the U.S. area. Note that labels for isobars have been added at their ends where they reached the boundary of the map area having plotted data or, for the small, closed 1012-mb isobar, placed in the line itself.

Answer 1

Ans.

I have shown here all the isobars with red color and the areas of high pressure (HP) and low pressure (LP) are also marked. at some places, the number was not clearly visible, I might have made mistake. if you get any problem in understanding, please leave a comment i will try my best to fix the query, Goodluck
