A variant of the operator integrating factor splitting originally proposed by Maday et al. (1990) is applied to a h-adaptive, non-conforming spectral element shallow water model over the sphere. The resulting algorithm is efficient and avoids any type of local time-stepping like in the Berger-Oliger algorithm. The model is tested against the shallow water cases proposed by Williamson et al. (1992). The numerical results show that it is possible to keep the semi-implicit time step constant while varying the advective time scale to meet the maximal Courant restriction.
