I would guess they'd probably be in an area they feel is habitatible.
Air masses form because of all the moisture in the air, and they redistribute energy on the Earth's surface because of the Sun's uneven heating on the Earth allowes more energy to Earth.
Explanation:
It is given that,
Momentum of the photon, 
(a) We need to find the wavelength of this photon. It can be calculated using the concept of De-broglie wavelength.

h is the Planck's constant


or

(b) The wavelength lies in the group of ultraviolet rays. The wavelength of UV rays lies in between 400 nm to 10 nm.
