An Investigative Study of the January Thaw Phenomenon

An Investigative Study of the January Thaw Phenomenon

Abstract:

A broad investigation of the January thaw phenomenon, a period of unseasonable warmth, was conducted
using daily maximum temperatures recorded at New Brunswick, N.J. from 1858-1976. Student’s t-tests
comparing long period means of maximum temperature to values form a fitted ‘seasonal trend curve’ indicate
temperatures higher, on the 22nd-23rd, and lower, on the 29th, than seasonally expected. Binomial tests
verified these at the 5% level. A thaw index was derived. The relationship of thaw intensity to zonal indices
and mean monthly temperatures was investigated using contingency, correlation, and student’s test analyses.
