    Everything's cooler?
    There's less interference?
    Alien spaceships don't fly at night?

    I don't really know. Give us a clue?

    Varying air pressures change the skin depth (the depth to which a certain EM wave can penetrate) so that would affect the strength of the signal you are receiving.

    The higher the pressure, the lower the skin depth and the worse the signal strength and vice versa. One would assume when you are getting a stronger signal the pressure is smaller.

    Also when it is night time the signal is not subject to any ionic interference (charged particles) from the sun as the Earth is shielding it so that would make the signal stronger as well - although the signal is still subject to interference from radiation from the cosmos (supernovae remnants etc).
