1. Surface Station Models

2. How do we decode these models?

3. Each model has common features
- Pressure tendency and/or station id can also be included to the right

4. Decoding Pressure A good rule of thumb….
A decimal point is always included between the last 2 digits, but does this make sense?...probably not
We want the pressure in mb
Generally, if the reading is >500, a 9 is placed in front of the SLP.
Example: if the pressure = 988, the decoded value would be mb.

5. Decoding Pressure (cont.)
If the reading is below 500, then we add a 10 in front of it.
Example: If the pressure = 238, the decoded value would be
Showing that this station is under the influence of high pressure
