Spring Has Sprung! Or Has It? The Math Behind Seasons

Yawn! That’s not my reaction to the title, but to the sleepiness that comes from giving up Lent, eating chocolate (provided at half price by Safeway on Easter Monday), and sleeping in after a sugar rush. Easter, is a Spring holiday – not by chance, but by design: Spring officially starts on the Spring equinox, and Easter falls on the first Sunday after the first full moon after the Spring equinox (unless bla bla). Since there is one full moon in every 29-something days, you are guaranteed to see Easter happen soon after the official start of Spring.

Yet, because I am a nerd, the first thing that comes to my mind is not Christ, the Lord and Savior returning, it’s not bunnies and chocolate, and it’s not even the painful reminder that the snowboarding season is almost over. In fact, the first thing that comes to my mind about every three months at the change of seasons is, “but the season has long started!”

Yes, all of March is relatively mild, despite the fact the first two thirds are officially winter. It’s the exact same thing for all seasons: June is already hot as all get-go, except maybe in San Francisco and Fairbanks, AK. September is my favorite month, and the hottest in San Francisco – but it’s the hottest there precisely because temperatures dip to its East. And finally, the cruelest joke of all, Christmas is close to the coldest day of the year, but it’s just the beginning of winter.

What’s the deal? Why do we assign some random point about a third of the way into the season as its beginning?

Let’s take the Winter solstice, traditionally falling around the 21st of December. It is the day with the shortest daylight duration. Before it the days were longer, and after it they will be shorter. Since our Earth relies on imported heat from the sun, the shortest daylight should coincide with the least heat. The coldest day of the year should be the Winter solstice!

Things aren’t that quick, since it takes the atmosphere some time to adapt to change, sort of like it’s been caught doing the naughties with the sun and needs to straighten out her dress. But, in fact, at least in Denver, the coldest day of the year is December, 26th, not even a week after the solstice. It is in fact very odd that we consider what should be the exact middle of winter, the beginning. Even when taking into account heat inertia, it makes very little sense to consider the solstice the beginning of the season instead of its middle.

But it’s convenient. The dates of equinoxes and solstices are constant, we need a day to start the seasons, might as well pick something that is somewhat related to them (even if the day picked should be the middle of the season by logic). Generally, it feels like the seasons should align more with the months (all of December, January, and February in winter, all of March, April, and May in spring, etc.), but who cares?

Well, your resident nerd cares. I went and decided I was going to compute when the seasons really begin and how long they really last!


Amazon Pilots: Onion News Network

Not at all what I was expecting. I thought the ONN would be a news show much like Jon Stewart’s immensely popular The Daily Show on Comedy Channel. Instead, it’s a scripted show about the ugliness of the daily news cycle. It stars an adorable set of characters in various stages of neurotic and reminds one more of a Legend of Ron Burgundy without charisma.

The main character is a poor shmuck imported from Indiana (a stand-in for rural America) to the Big Apple, where he wants to make it big in news. The whole world makes of him, but in the end he gets his break and gets the job he’s been craving. The protagonist is a familiar actor, Christopher Masterson, who used to be Francis, the oldest of the kids in Malcolm in the Middle.

Chasing Mavericks (2012)

<youtube>jh09vEGNrXc</youtube>Everybody had been telling me I should watch Chasing Mavericks, but I somehow didn’t feel inclined. Surf movies – and movies about surfing, which is not the same thing – tend to be depressingly fictionalized. They portray the world as a surfer would love it to be, and not as it is. The waves are always perfect, the bros are always on a spiritual quest of communion with the ocean, and somehow there are always more ladies in the water than anyone has witnessed in a lifetime.

Big wave surfing, which is what Mavericks is famous for, is then the ultimate of the type. Big wave conditions are exceedingly rare, especially in California; until recently the sport was extremely exclusionary; and there were virtually no big wave surfers that were also women. Testosterone drove the sport, and it showed.

Last night, someone decided we should watch Chasing Mavericks, and I reluctantly agreed. I was pleasantly surprised.

California has a bad angle for the giant storms from Alaska: our coast goes (at least in the more populated Southern half, which includes the Bay Area) North-West to South-East, which is almost parallel to the path of the storms. That makes for storms that soak out coast from Eureka to San Diego, but it also makes for fairly short windows of wave action. Since the winds go with the coast, you only get storm surf when the wind is blowing.

For the longest time, people thought there could not be a big wave in California, because there was no coast that was perpendicular to the waves (like Jaws in Maui). There were rumors of a big wave spot near Santa Cruz, but nothing confirmed. Then, seemingly overnight, a place called Mavericks became famous and crowded. Its enormous (occasionally 40-foot) waves were tempting, especially because Santa Cruz has a fairly big surfing community and there was no other giant wave anywhere else.

The story told in the movie is that of Jay Moriarty, an actual grom who became instantly famous when a shot of him dropping into a Mavericks wave made the front cover of Surfer magazine in the olden days. I do not know how close the story is to actual events, but a cameo recording of Moriarty at the end makes it clear the movie was a hommage.

In the movie, Jay is first rescued by a surfer dude from certain drowning. The dude in a tell-tale VW minibus drives the kid and his best (girl)friend home. It turns out he lives just across the street.

Jay has a hard time. He is obsessed with waves and the ocean, possibly because nothing else is working in his life. His father left the family for undisclosed reasons, the mother is bordering depression and gets sequentially fired for misconduct (mostly tardiness) at all her jobs. School isn’t working well, either. 

He discovers surfing as a way out of everything. He makes enemies in the water, in particular a sinister youth that feeds his anger with a baseball bat. He makes friends in the water, too, including his best friend, who’ll stick with him through thick and thin.

One day, though, he hears the same surfer neighbor leave in the early morning, and he jumps on the back of the minivan. When he reaches their destination, he gets off and watches a group of four surfers paddle out. His neighbor, Frosty, catches one of the giants and Jay yells in admiration. Frosty notices and expresses his dismay on the way back: Mavericks is a secret, and it better stay that way. Jay agrees not to tell anyone, but he wants to surf that wave, himself.

Long story short, Frosty finally agrees to train Jay. But instead of training for the wave, they will train against its dangers. A grueling regime of paddling, ocean watching, breath holding follows that fills out the center section of the movie. Then, when it’s finally time for Jay to make it out, news breaks of the break, and suddenly the place is crowded. Will Jay make it? Will someone die? Who survives the crazy wave? No spoilers here.

What worked for me about the story was that it didn’t gloss over the routine douchyness of surfers. The very first shot at the Santa Cruz harbor includes Sonny, the antagonist, shoving a surfer from his board while dropping in on him. Surfing is (correctly) portrayed as something you mostly enjoy with few people around, mostly because when there are many people, there is always the idiot that spoils it for everyone.

The love for the ocean that propels surfers is part of it, too. I do not obsess like Jay, who would routinely pass out in class because he was training holding his breath. But to this day, two years into surfing, I still can’t watch a wave without staring at it. I will see the wave and I will instantly want to be in the water, no matter what else is going on in my life.

The scenery and ocean shots are splendid. The California coast is a gift to humanity, and the movie captures its rugged beauty well. Also, the general poverty of the characters is portrayed in a realistic fashion and not glossed over. The ramshackle houses of Jay’s and Frosty’s family have cupboards whose hinges are coming unglued; you would not be surprised to see a rat pop up.

The acting is a bit uneven. Jay, in particular, doesn’t really develop much of an expressiveness. His range is limited to “overwhelmed,” no matter what goes on. When his best friend (SPOILER!) betrays him, he looks overwhelmed, not angry and sad. When his mother turns out (more SPOILER!) to have cleaned up her act and saved up for his birthday, he looks overwhelmed. When his childhood sweetheart (you got it, SPOILER) confesses her eternal love, he looks overwhelmed.

Frosty, played by the masterful Gerard Butler, is a whole different ball game. He does very well as the rugged older man, the wise Yoda, who will mentor Jay thoughout his attempts.

Sonny, the antagonist, does his anger well, but could have played his motives better. In particular he fails to convey anything at the very end (not gonna spoil it).

I’ll say, of all movies about surfing, this is one of my favorites.
