How to enter the temperature that varies with time??

Due to the variation in air velocity, the external temperature varies with time. Can I know how can I input the values using an equation or an excel sheet??

This might help. I've include my mph file stripped of geometry and mesh, but with the pressure and temperture pulse as analysitic functions. I also have temperture dependent properties. It fiar easy to define an analytic function in the global definitions and simple input the name of that function either as a temperture vs time boundary or as an function temperature time depentent ambient function. The is a structural-heat transfer problem but the procedures should be the same.

I deleted the geometry and mesh as not relevant to the problem,
