Do pine trees have different yearly cycles where one year produces tons of needles and the next year cones?

This year I have a ton of pine needles, where as last year I had a ton of pine cones. Do these trees cycle yearly like this?

Some species of pine have male and female trees (most are unisexual, both male %26amp; female) The females take a year or so to develop mature cones after being pollenated. I would think you may have a female that is being pollenated by a nearby male. Males also develop cones but theirs are yearly and fall off shortly after releasing pollen. So in theory, your tree may have a bumper crop of cones every 2nd or 3rd year. Your best bet would be to find out what kind of pine it is to know for sure.
