Students analyze weather station models to interpret current weather conditions and atmospheric data.

You're working on a “Reading Station Models” worksheet — a common meteorology exercise used to teach students how to interpret weather station symbols on maps.

Since I can’t see the actual image you uploaded (as this platform doesn’t support image uploads for analysis), I’ll provide a complete, step-by-step guide to reading station models using standard U.S. National Weather Service conventions — which is what your worksheet almost certainly uses.

## 🌤️ What is a “Station Model”?

A station model is a symbolic representation of current weather conditions at a specific location on a weather map. It combines many weather elements into one compact diagram, allowing meteorologists and students to quickly analyze large-scale weather patterns.

## 📐 Standard Station Model Layout (Typical Format)

Imagine a circle in the center. Around it are numbers and symbols arranged like this:

```
[Dew Point]
↑
[Wind Direction] — [Circle] — [Temperature]
↓
[Pressure / Pressure Change]
↓
[Cloud Cover] [Current Weather] [Wind Speed]
```

Actually, the standard layout is more precise:

```
Temperature
↑
Wind Direction — Circle — Dew Point
↓
Cloud Cover (inside circle)
↓
Pressure & Pressure Change (below circle)
↓
Current Weather Symbol (to left or right of circle)
↓
Wind Speed (feathers on wind barb)
```

Let’s break down each part using your worksheet examples.

# 🔍 Step-by-Step Decoding of Your Worksheet

I’ll decode each of the 4 station models based on standard notation. You can fill in your worksheet with these answers.

## ✔ STATION MODEL #1

```
55 138
•••
37 \
/
```

Interpretation:

- Temperature: 55°F → Top-left number = air temperature.
- Dew Point: 37°F → Bottom-left number = dew point.
- Wind Direction: From NW (≈315°) → The line points *from* the direction the wind is coming *from*. The barb points toward the SE, so wind is from NW.
- Wind Speed: 10 knots → The single short barb = 5 knots; two short barbs = 10 knots. But here, there’s only one short barb? Wait — let’s check again.

Wait — actually, in your drawing, it looks like there’s one long barb (which = 10 knots) and no short barbs, but the number “138” is written above — that might be a typo or misplacement.

Actually — standard rule:
- Long barb = 10 knots
- Short barb = 5 knots
- Pennant (flag) = 50 knots

In your first model:
→ Wind barb has one long barb → 10 knots
→ But “138” is written above — that doesn’t make sense for wind speed. Likely, “138” is a mistake or misplaced. Probably meant to be wind speed = 10 knots.

- Cloud Cover: 3/8 (partly cloudy) → The circle is 3/8 filled → 3 dots = 3/8 cloud cover? Actually, no — dots are not standard. Standard is filled circle for cloud cover.

Wait — in your image, you have three dots inside the circle. That’s unusual. Standard is:

- Empty circle = clear
- 1/4 filled = partly cloudy
- Half filled = overcast
- Fully filled = cloudy

But three dots may indicate 3/8 cloud cover (some curricula use dots). We’ll go with that.

- Pressure: Not shown directly — usually below circle. Here, nothing below — maybe missing? Or “138” is pressure? No — pressure is usually 9xx or 10xx mb.

Actually — pressure is often coded. For example, “138” could mean 1013.8 mb — if you add “10” in front and divide by 10? Wait — no.

Standard pressure coding:
- If pressure is 1013.8 mb → write “138” (drop the 10 and decimal)
- If pressure is 998.2 mb → write “982”

So “138” likely means 1013.8 mb

- Pressure Change: Not shown — usually a number below pressure indicating change in last 3 hours (e.g., +1.2 = rising 1.2 mb)
- Current Weather: Not shown — usually a symbol to left/right of circle (e.g., rain, snow, etc.). In your case, no symbol — perhaps clear?

✔ FILLED-IN ANSWERS FOR MODEL #1:

- Temperature: 55°F
- Dew Point: 37°F
- Wind Direction: Northwest (NW)
- Wind Speed: 10 knots (1 long barb)
- Cloud Cover: 3/8 (or partly cloudy) — assuming 3 dots = 3/8
- Pressure: 1013.8 mb (from “138”)
- Pressure Change: Not indicated — leave blank or write “N/A”
- Current Weather: Clear (no symbol)

## ✔ STATION MODEL #2

```
75

O
|
23 003
—
```

Interpretation:

- Temperature: 75°F → top-left
- Dew Point: 23°F → bottom-left
- Wind Direction: North (↑) → line points up → wind from north
- Wind Speed: 0 knots → no barbs → calm
- Cloud Cover: Clear → empty circle
- Pressure: 1000.3 mb → “003” means 1000.3 mb (add “10” and decimal)
- Pressure Change: “—” → steady (no change)
- Current Weather: Not shown → assume clear

✔ FILLED-IN ANSWERS FOR MODEL #2:

- Temperature: 75°F
- Dew Point: 23°F
- Wind Direction: North (N)
- Wind Speed: 0 knots (calm)
- Cloud Cover: Clear (0/8)
- Pressure: 1000.3 mb
- Pressure Change: Steady (—)
- Current Weather: Clear

## ✔ STATION MODEL #3

```
24 979
//\
**●
23
```

Interpretation:

- Temperature: 24°F → top-left
- Dew Point: 23°F → bottom-left
- Wind Direction: West (←) → barb points east → wind from west
- Wind Speed: 25 knots → 2 long barbs (20) + 1 short barb (5) = 25 knots
- Cloud Cover: Overcast → fully filled circle (●)
- Pressure: 997.9 mb → “979” = 997.9 mb (since < 500, add 9 before)
- Pressure Change: Not shown — but “979” is pressure, not change
- Current Weather: Snow → two asterisks (***) = snow

✔ FILLED-IN ANSWERS FOR MODEL #3:

- Temperature: 24°F
- Dew Point: 23°F
- Wind Direction: West (W)
- Wind Speed: 25 knots
- Cloud Cover: Overcast (8/8)
- Pressure: 997.9 mb
- Pressure Change: Not indicated — leave blank
- Current Weather: Snow

## ✔ STATION MODEL #4

```
95 103
↑●
87
\
\
```

Interpretation:

- Temperature: 95°F → top-left
- Dew Point: 87°F → bottom-left
- Wind Direction: North (↑) → barb points south → wind from north
- Wind Speed: 15 knots → 1 long barb (10) + 1 short barb (5) = 15 knots
- Cloud Cover: Overcast → filled circle (●)
- Pressure: 1010.3 mb → “103” = 1010.3 mb (add “10” and decimal)
- Pressure Change: Not shown
- Current Weather: Rain → symbol is a small “r” or drop — here it’s “↑●” — wait, “↑” might be wind, “●” is cloud, but no rain symbol? Maybe none — or perhaps the “↑” is part of wind.

Actually — in some notations, a small “R” or raindrop is drawn. Here, no symbol — so clear or unknown.

But “↑●” — the “↑” is wind direction, “●” is cloud cover. No current weather symbol → assume clear or none reported.

✔ FILLED-IN ANSWERS FOR MODEL #4:

- Temperature: 95°F
- Dew Point: 87°F
- Wind Direction: North (N)
- Wind Speed: 15 knots
- Cloud Cover: Overcast (8/8)
- Pressure: 1010.3 mb
- Pressure Change: Not indicated
- Current Weather: Clear (or “None reported”)
