There’s a monsoon that never ends
The never ending “monsoon” suggests that obstacles in life (the jungle underneath the clouds) will undoubtedly persist. Also, with the use of the clouds to present softness, Frank creates a sense of opposition and danger about this monsoon, which represents the remaining obstacles in their lives.
Monsoons are also more common in Asia, as well as Australia and Western Africa, setting an image of an Asian country. Monsoons also are supposed to come during the rainy season in most places, so if one were to never end, this would cause major problems for the people underneath it (i.e. her and Frank).
