Abstract
The climate of the Canadian Arctic determines response in ice cap and glacier mass balance. Our ability to predict mass balance change depends on understanding the relationship between climate variability and ice caps. This paper investigates climate variability in the Canadian Arctic, established by analyzing temperature records from a 1977-1999 WMO coastal weather station dataset, the NCEP-NCAR Reanalysis temperature dataset, and 1948-2000 precipitation records from the Meteorological Service of Canada. Temperature analyses are extrapolated from coastal weather stations to ice cap elevations by comparing the WMO temperature dataset to the NCEP-NCAR Reanalysis at 1000 hPa and then calculating environmental lapse rates based on NCEP-NCAR Reanalysis temperature values at 850, 700, and 500 hPa. Temperature and precipitation anomalies from 1995-1999 are discussed in detail to provide explanations for ice cap elevation changes measured by the Arctic Ice Mapping (AIM) laser altimetry/GPS measurements of 1995 and 2000.
