What do you call bouts of sunshine and no rain. ?

[modeller]

We all know what showers are , intermittent periods of rain. but what single word describes , intermittent periods of sunshine.
Today we have had half hour periods of sunshine followed by half hour periods of dark clouds and strong winds but not a spot of rain and it occurred to me we don't have a single word to describe that weather condition.

The word 'mixed' would cover it, though that word is also used to describe other conditions, such as rain alternating with snow.

Good letter in the Daily Telegraph last week where someone asked if pensioners are going to get a Summer Heating Allowance!

Yes, there's no single word, but I would expect forecasters or reporters to call that "bright periods".
