Precipitation enhancement over a low coastal hill in winter is demonstratedfor particular associations of synoptically determined onshore airflow andlocal geography encountered over south-eastern Newfoundland. Four suchcases, involving a mixture of pre-warm-frontal precipitation types atsurface temperatures just below freezing, are analysed using comparativesurface gauge records from sites at the coast and hill summit and detailedvolume scan data from a Doppler radar. Whilst precipitation at the hillsummit and upwind coast was of similar overall duration in each case, thesurface rates on the hilltop exceeded those at the coast by 1.0-4.0 mm h-1during different stages of the events. Analysis of the Doppler reflectivitypatterns reveals that intensities are especially enhanced near the windwardhill crest, supporting the observed association of greatest enhancement with astrong local upslope wind component exceeding 20 m s-1. In themajority of these cases the enhancement is maintained primarily by the ‘seeder-feeder’ mechanism, which appears to be acceleratedduring precipitation transitions and with the surface warm front 120-150 kmdistant; however, a preliminary phase of enhancement due to topographicallyinduced uplift of stable pre-frontal air is also recognised in one case.
