Why Do The Seasons Lag Behind The Calendar?

SEATTLE - Statistically, Seattle is at its warmest in late July and its coldest in late January. But the first day of summer is in late June and winter starts in December, so why the lag time?

Just like a pot of water doesn't boil the instant you turn on the heat, the atmosphere takes some time to warm up or cool down, as the case may be. Even though we get the most daylight in late June, it takes about 30 days for the atmosphere to transfer that maximum warmth to the surface. The same, but opposite effect works in winter.

The oceans and lakes take even longer to respond to heating and cooling. They typically take until late September to be at their warmest, and late March to be at their coldest.

When I saw this dramatic cloud to the north, it reminded me of smoke, rising in billows until it hits the jet stream, then it's pulled hundreds of miles east. I had to capture it quickly. Within minutes the effect had faded.

For my girlfriends birthday we had a party at her parents. We knew the nest was there but the owner hadn't seen or heard the osprey for a day or two. He asked me to fly my drone up and see if any was wrong. I flew up and found that there were two eggs inside.
