Title: Observation of muon intensity variations by season with the MINOS Near Detector

A sample of 1.53$$\times$$10$$^{9}$$ cosmic-ray-induced single muon events has been recorded at 225 meters-water-equivalent using the MINOS Near Detector. The underground muon rate is observed to be highly correlated with the effective atmospheric temperature. The coefficient $$\alpha_{T}$$, relating the change in the muon rate to the change in the vertical effective temperature, is determined to be 0.428$$\pm$$0.003(stat.)$$\pm$$0.059(syst.). An alternative description is provided by the weighted effective temperature, introduced to account for the differences in the temperature profile and muon flux as a function of zenith angle. Using the latter estimation of temperature, the coefficient is determined to be 0.352$$\pm$$0.003(stat.)$$\pm$$0.046(syst.).
