Cloud Type Identifier

Match an uploaded cloud photo against the 10 standard WMO cloud genera and read its meteorological meaning.

Live tool

Best match
Cumulus

Fair weather; convection building. Watch for vertical growth.

Introduction & principle

Uses the WMO International Cloud Atlas taxonomy. The tool compares dominant visual features (base height, layering, vertical development, edges) you select against canonical descriptors for the ten cloud genera: Cirrus, Cirrocumulus, Cirrostratus, Altocumulus, Altostratus, Nimbostratus, Stratocumulus, Stratus, Cumulus, Cumulonimbus.

Tool advantage

Mainstream weather apps stop at 'cloudy'. This tool teaches the actual cloud genus and what it forecasts locally.

Detailed usage guide
  1. 1Upload a single cloud photograph taken from below in good light.
  2. 2Pick the dominant base height: low (< 2 km), middle (2–7 km), high (> 7 km).
  3. 3Select observed features such as vertical development, layered sheet, fibrous strands.
  4. 4Read the matched genus, weather implication, and likely follow-on conditions.
Common problems & FAQ

Why is my photo classified as more than one type?

Multi-layer skies often contain two or three genera at once. The tool lists the most probable match and a runner-up.

Does the photo get uploaded to a server?

No. Identification runs in the browser. The image never leaves your device.
