The two key climate parameters are
ablation season temperature and accumulation season precipitation.
We examined
ablation season temperature for five regional weather stations and for two different month combinations (May - September and June - September) and found the Diablo Dam record for June - September to provide the best correlation.
Annual
ablation season temperature is rising and accumulated snowpack, April 1 SWE is declining.
The four primary climatic variables affecting North Cascade glaciers are
ablation season temperature, accumulation season precipitation, summer cloud cover and May and October freezing levels (Tangborn, 1980; Pelto, 1988).
1) Mean
ablation season temperature has been 1.1 oC above the long term mean (1950 - 1980).
The correlation between annual net balance is higher for
ablation season temperature than for accumulation season precipitation.
Not exact matches
During the
ablation season four climate variables were used 1) May - August mean
temperature, 2) May - September mean
temperature, 3) June - August mean
temperature, 4) June - September mean
temperature.
The accumulation
season precipitation October - April averages 3300 mm and the
temperature during the
ablation period averages 8.1 °C.
