### features.

$$
H = \frac{k_BT}{\omega m_H g}
$$

1. solid or dash
   solid q

2. larger mean molecular weights?
   B: shallow features <span>&rArr;</span> higher mean molecular weights

mass-metallicity trend

> \[!question\] Question
>
> Can we detect clouds in exoplanets?

Clouds suppress atmospheric chemical signatures

> \[!tip\] Important
>
> Introduced a degeneracy between <mark>cloud-top pressure</mark> and <mark>mean molecular weight</mark>

### clouds/winds on giant planets.

Wind cells

Hadley cells

> \[!note\] Coriolis Effect
>
> Winds do not follow a straight trajectory
