ABSTRACT: The variation in
temperature on the island of Gran Canaria is studied using the method applied
to the nearby island of Tenerife [1]. An upward warming trend of 0.09°C ± 0.05°C (α = 0.01) was seen from 1946 to date,
which has accelerated since the seventies to 0.17°C ± 0.10°C (α = 0.01). The
increase was higher at night (0.11°C ± 0.05°C) than by day (0.08°C ± 0.06°C),
so the temperature range decreased slightly. These values are similar to those
of Tenerife and the time series of anomalies for the two islands are highly
correlated. On the coast the same relationship to the sea surface temperature
was found as in Tenerife, but in the mid-altitude areas to windward, some differences were detected that are
hypothetically attributable to the different relief of the two islands.
