Spotting features on a weather map worksheet from the Royal Meteorological Society and University of Reading.

This is a weather map interpretation worksheet from the Royal Meteorological Society and University of Reading. The goal is to identify specific weather features on the synoptic chart (the large map) and match them with numbered pink markers (1–14), and also to match four photos (A–D) with their corresponding weather conditions.

## 🌍 PART 1: IDENTIFYING WEATHER FEATURES ON THE MAP (Pink Numbers 1–14)

We’ll go through each numbered point and identify what feature it represents based on standard synoptic chart symbols:

🔹 1 — Warm front

- Symbol: Red line with semi-circles pointing in direction of movement.
- Location: Over eastern Europe, moving northeast.
- Answer: Warm front

🔹 2 — Low pressure / Depression

- Symbol: “L” at center of closed isobars with inward spiraling winds.
- Located over central Europe (near 976 hPa).
- Answer: Depression (also called Low pressure)

🔹 3 — Cold front

- Symbol: Blue line with triangles pointing in direction of movement.
- Located over northern UK/Ireland, moving east.
- Answer: Cold front

🔹 4 — Occluded front

- Symbol: Purple line with alternating triangles and semi-circles.
- Found where cold front overtakes warm front — common in mature low-pressure systems.
- Located near center of depression (2), wrapping around it.
- Answer: Occluded front

🔹 5 — High pressure / Anticyclone

- Symbol: “H” at center of closed isobars with outward spiraling winds.
- Located over Scandinavia (1023 hPa).
- Answer: High pressure (also called Anticyclone)

🔹 6 — Southwesterly wind

- Wind barbs show direction wind is coming FROM.
- At position 6, barbs indicate wind blowing from SW → NE.
- Answer: Southwesterly wind

🔹 7 — Light wind

- Wind barbs have only one short feather → 5 knots or less.
- Near 1008 hPa isobar, over France.
- Answer: Light wind

🔹 8 — Strong wind

- Wind barbs with multiple feathers (e.g., 2 long + 1 short = 25 knots).
- Near the center of the depression (2), indicating strong winds due to tight pressure gradient.
- Answer: Strong wind

🔹 9 — Northerly wind

- Barbs point south → wind coming from north.
- Over Norway/Sweden area.
- Answer: Northerly wind

🔹 10 — Northwesterly wind

- Barbs point southeast → wind from NW.
- Over North Sea, between UK and Scandinavia.
- Answer: Northwesterly wind

🔹 11 — Anticyclone

- Same as #5 — “H” symbol with high pressure (1023 hPa).
- Answer: Anticyclone (or High pressure — both acceptable, but worksheet lists both separately; likely “Anticyclone” for this one since #5 is “High pressure”)

> ✔ Note: “Anticyclone” and “High pressure” are synonyms. Worksheet may want you to assign one to #5 and one to #11. Since #5 is clearly labeled H, and #11 is also H, we can say:
> - #5: High pressure
> - #11: Anticyclone

🔹 12 — Low pressure

- “L” symbol over southern Spain/Portugal region (992 hPa).
- Answer: Low pressure

🔹 13 — Cold front

- Another blue line with triangles, extending southwest from the main depression.
- Answer: Cold front

🔹 14 — Warm front

- Red line with semi-circles, extending northeast from the depression.
- Answer: Warm front

## 📸 PART 2: MATCHING PHOTOS A–D TO WEATHER CONDITIONS

Now let’s analyze the photos:

🖼️ Photo A: Dark, heavy rain clouds — likely nimbostratus or storm clouds.

- Associated with warm front or occluded front — steady, widespread rain.
- Best match: Warm front or Occluded front

> But looking at the worksheet, we need to pick *one* condition per photo.
> Photo A shows heavy precipitation — typical of warm front (steady rain ahead of it).

✔ Photo A → Warm front

---

🖼️ Photo B: Puffy white cumulus clouds, blue sky — fair weather.

- Typical of high pressure / anticyclone.
- Clear skies, light winds, stable air.

✔ Photo B → High pressure

---

🖼️ Photo C: Grey, uniform overcast sky — no sun, no distinct clouds.

- Classic stratiform cloud cover — associated with warm front or occluded front.
- But Photo A already took “Warm front”. Let’s check…

Wait — Photo C looks more like stratus — often seen under warm front or occluded front. However, if Photo A is heavy rain (likely warm front), then Photo C might be occluded front (which can bring prolonged drizzle).

But let’s think differently:
Photo C could also represent low pressure system — cloudy, gloomy, no direct sun.

Actually, better fit:
Photo C → Low pressure (overcast, dull conditions)

✔ Photo C → Low pressure

---

🖼️ Photo D: Wispy, high-altitude cirrus clouds — fair weather, but may indicate approaching front.

- Often seen ahead of warm front (but not raining yet).
- But Photo A is already warm front with rain.

Alternatively, these are fair weather clouds, sometimes seen in anticyclonic conditions.

But Photo B is already high pressure with cumulus.

Wait — Photo D has very thin, feathery clouds — cirrus — which often precede a warm front by 12–24 hours.

Since Photo A is active rain (warm front), Photo D could be ahead of warm front — still technically warm front influence.

But worksheet likely wants distinct matches.

Let’s reassign:

- Photo A: Heavy rain → Warm front
- Photo B: Fair weather cumulus → High pressure
- Photo C: Grey overcast → Occluded front (prolonged drizzle)
- Photo D: Cirrus → Cold front approaching? Not really — cirrus usually precede warm fronts.

Actually, Photo D is classic fair weather — perhaps light wind or anticyclone.

But Photo B already has high pressure.

Alternative idea: Maybe Photo D is strong wind? No — no indication of wind.

Let’s look at the worksheet again — it says “Photo A”, “Photo B”, etc. — we must assign one condition per photo.

Best logical assignment:

✔ Photo A → Warm front (rainy conditions)
✔ Photo B → High pressure (sunny, fair)
✔ Photo C → Occluded front (grey, drizzly)
✔ Photo D → Light wind (calm, wispy clouds — suggests light wind)

> Why? Because cirrus clouds form in high, stable air — often with light winds aloft. And the sky isn’t stormy or overcast — so not low pressure or front directly overhead.

Alternatively, if “Light wind” is too vague, maybe Northwesterly wind? But no visual cue.

I think Photo D → Light wind is reasonable.

## ✔ FINAL ANSWERS

For Pink Numbers 1–14:

| Number | Feature |
|--------|----------------------|
| 1 | Warm front |
| 2 | Depression |
| 3 | Cold front |
| 4 | Occluded front |
| 5 | High pressure |
| 6 | Southwesterly wind |
| 7 | Light wind |
| 8 | Strong wind |
| 9 | Northerly wind |
| 10 | Northwesterly wind |
| 11 | Anticyclone |
| 12 | Low pressure |
| 13 | Cold front |
| 14 | Warm front |

> Note: #1 and #14 are both warm fronts — that’s fine; they’re different segments of the same front system.

For Photos A–D:

| Photo | Feature |
|-------|----------------------|
| A | Warm front |
| B | High pressure |
| C | Occluded front |
| D | Light wind |

## 🧠 EXPLANATION SUMMARY

- Fronts: Cold fronts (blue triangles), warm fronts (red semi-circles), occluded fronts (purple alternating symbols) — all shown on the map.
- Pressure systems: “L” = low pressure/depression; “H” = high pressure/anticyclone.
- Wind direction: Determined by wind barbs — arrows point to where wind is going; barbs show speed and direction it’s coming FROM.
- Photos: Matched to most visually representative weather condition — e.g., rainy = warm front, sunny = high pressure, grey overcast = occluded front, wispy clouds = light wind.

This exercise helps students learn to read synoptic charts — essential for understanding real-time weather patterns!
