Mach number temperature generally decreases with increasing altitude between sea level and , the speed of sound also decreases. For example, the standard atmosphere model lapses temperature to at altitude, with a corresponding speed of sound (Mach1) of , 86.7% of the sea level value. While the terms "subsonic" and "supersonic", in the purest sense, refer to speeds below and above the local speed of sound respectively, aerodynamicists often use the same terms to talk about particular ranges of Mach values. This occurs because of the presence of a "transonic regime" around M = 1 where approximations of the Navier-Stokes equations used
Mach Rider Blue, further reinforcing the connection between the two series. The remix returned in later titles "Super Smash Bros. Brawl" and "Super Smash Bros. for Wii U". There is also a collectible Mach Rider trophy in "Melee", and a Mach Rider sticker in "Brawl". In "Mario Kart Wii", a vehicle called the "Mach Bike" resembles the bike in "Mach Rider". In addition, a similar vehicle also appeared in "Mario Kart 8", known as the "Sport Bike". In "", one of the many minigames is based on "Mach Rider". Mach Rider It was released on the Virtual Console for the Wii (2007),
