It looks as if I have must expressed myself insufficiently clear in my last
mail. Of course I know that 'summer' is defined by various metereological
rules, and not by temperatures, So summer comes every year, regardless of
the weather, also in Tromsø. The last days we have had virtually 24 hrs of
sunlight (we still have the midnight sun), so also under that (for me
somewhat strange definition) we have summer here now.
My last mail was subjected 'Still no real summer weather in Tromsø', but
unfortunately the word 'weather' was inadvertently omitted in the heading.
Sorry about that!! It is 'summer weather' we talk about here in Tromsø when
the temperature comes above 20'C; this definition is used all over Norway,
by the way, just as we in this countrytalk about 'tropical nights' when the
temperature does not sink below 20*C at night---we have had such nights in
Tromsø too, but very few of them and of course none this summer.
In reality I suppose what constitutes summer weather depends on what is the
normal for that particular place. Further south in Europe 'summer
temperatures' may be those above 25*C, and on Svalbard probably those above
8*C! (Just as they told me in Bhutan; 'everything below 5000m a.s.l. we call
foothills', while here in Tromsø we have mountains of 1200m)
Another misunderstanding: I never said that the lask of summer weather
interferes with nesting success of out birds; it does not, although both
birds and flower are several weeks later than most other years.
I clearly need to work on my English!
