Question

State the cloud sequence in order if you are approaching a stable warm front from the cold air side:

a) Ci, As, Ac, Ns, St
b) St, Ns, Ac, As, Ci
c) Ci, Cs, As, Sc, Ns
d) Ns, Sc, Ci, Cs, Ac

Answer 1

The correct cloud sequence when approaching a stable warm front from the cold air side is Ns, Sc, Ci, Cs, Ac.

Step-by-step explanation:

The correct cloud sequence when approaching a stable warm front from the cold air side is Ns, Sc, Ci, Cs, Ac.

When approaching a warm front, the first cloud type that typically forms is Nimbostratus (Ns). This is a thick, gray cloud that brings continuous, steady rain. As you continue to approach the warm front, you may then encounter Stratocumulus (Sc), which are lower, gray clouds that may appear in rows or patches.

Next, you would encounter Cirrus (Ci), which are high, wispy clouds. These clouds indicate that the warm front is nearby. Continuing closer to the warm front, you may then see Cirrostratus (Cs), which are thin, high clouds that can cover the sky. Finally, you may encounter Altocumulus (Ac) clouds, which are middle-level clouds that are often gray or white patches or layers.
