Thanks to the Sun, life on Earth continues. One of the major sources for energy on Earth is the Sun. Each has its own properties and fuel processes that make aspects of life possible, including driving a car or burning a fire. Sun path diagrams aren't the only thing you should be ready for one exams.From kinetic and potential to chemical and sound, various forms of energy exist on our planet. At this latitude you can see May and June lines are really close, so it's going to be more difficult to find an exact date, but it won't matter much either because the sun position is so similar already. Note: Original question asked about June 5th.
April 4th is 17 days away from April 21 and 14 days away from March 21, so it's just under halfway between the month lines for March and April, and slightly closer to the March line. If you want a specific day that's not the 21st you need to interpolate the sun path for that date. The chart shows the 21st of each month because the Solstices and Equinoxes fall on these days. QUESTIONS ABOUT SUN PATH DIAGRAMS What about the rest of the days that are not shown? April 4th for example? Good advice for the ARE and real life.Ĭan't read this blog because you're driving? I have a video you can watch instead! Unless you are specifically told otherwise, or the diagram only shows degrees from the South, you can assume you reference North. It means pay attention to the diagram! I did not encounter a question where I had to literally type in or multiple choose an altitude…I did have a few questions where you had to understand the sun position so you could figure out where shadows were. Sun path diagrams: what does this mean for the ARE? I was going to give SWL a pass, because maybe they were in the Southern hemisphere, except the entire chart is for 32° North Latitude, so a person using this chart would most certainly be referencing North. If you want to be a normal person, you would say the azimuth is 120° because a normal person would report the azimuth from the North. In our example, instead of saying the azimuth is 60° you should say it is “60° East of South” to make it known you are using South as a reference. Since referencing azimuth from the north is the standard if you were referencing it from the South you should specifically mention that. BUT, if you were to provide that information to someone who didn't have access to this exact chart, they would most likely think you were talking about a position that was generally Northeast. According to their chart, you would read the Azimuth as 60°.
Here's where I find Sun, Wind and Light annoying and not entirely correct. To find the azimuth of the sun, draw a line from the center to the outer edge of the chart, going directly through the sun position you marked. North is 000, East is 90°, South is 180°, West is 270° and then of course you get every 10 dgerees in between. You can read the direction/azimuth on the outer edge of the chart.
These are the thin lines radiating out from the center. A typical compass will show the cardinal directions (N, E, S, W) and provide a direction line every 10 degrees. 99.875% of the time this reference point is North, at least for those of us that live in the northern hemisphere. The azimuth is the angle of the sun from some reference point. Step 4: Find Azimuth Step 4: FIND THE AZIMUTH
