Understanding Isobars: A Visual Guide to Drawing Lines of Equal Pressure and Wind Movement, Exercises of Earth Sciences
This slide show provides step-by-step instructions on how to draw isobars around high and low pressure centers, along with illustrations of wind movement. Users are guided to encode pressures, label high and low pressures, and draw corresponding isobars. The presentation also explains the wind directions around highs and lows.
What you will learn
- How do you encode pressure values for drawing isobars?
- In which area are wind speeds the greatest?
- What are the wind directions around a low pressure system?
- What is the general relationship between wind direction and pressure?
- What are the wind directions around a high pressure system?

ISOLINE ACTIVITY:
**1. In PEN, uncode each pressure: 103= 1010.
- In PENCIL, label the highest pressure H** **and the lowest pressure L.
- For the H draw the following isobars:** **1016, 1012, 1008 mb
- For the L draw the following isobars:** **996, 1000, 1004 mb
- For each wind indicator- show wind** movement.
