Summer Swell/Weather Predictability

Hmmm... I don't really think it is easier to predict swells in the winter.

 

I see your point... But, the change in the upcoming south swell, is basically because it is one of those S/SW swells, where a change in the track which creates more W in the swell has a big influence for this region. This happens a lot in the winter too, all though the storm systems are generally much stronger in the winter and maybe a little easier to track as they move across the country.

 

The frontal systems are stronger in the winter for the Northern Hemisphere, because the temperature gradient from North to South is greater. This also allows the jet stream to drop down further with potential for storms to dip into the Gulf of Mexico moisture/energy source.

 

Cold Water holds more energy than warm water.

 

lmao don't give him stupid answers, he actually wants to know

 

incorrect.

 

True Dat,Look when Hurricane season is.

 

Just to clarify what sniffer said, cold water is more dense, packing more punch. So a 3ft wave in warm water has less kinetic energy than a 3ft wave in cold water. Studies have shown erosion rates of rocky coastlines are higher in cold water regions than warm water regions... same rock type, same average wave size.

 

It is a fact...look it up.

 

I think you need to stop using single letters for words and maybe pick up a book to learn something new.

 

The warmer the water is, the more latent heat is released into the atmosphere, which is the process by which tropical storms develop. Frontal system low pressure systems, however behave differently then tropical storms, and latent heat isn't required for frontal systems to develop and strengthen.

 

The temperature of the water, does influence the density of the water, but not only minimally influences wave energy traveling through the water. The lower the temperature, the less dense the h20 molecules become. Just think of an ice cube floating to the top of your glass of water.

 

The confusion is over the KIND of energy you're talking about. Kinetic energy (relating to water density, motion, and the force created as the wave breaks... which surfers refer to as "heaviness") vs. heat energy. Clearly, warm water has more heat energy, and that relates to what Swellinfo is talking about.

 

As Swellinfo stated: Water temperature is directly proportional to kinetic energy. In other words, when temperature increases, kinetic energy increases.

"Temperature directly relates to the kinetic energy of the molecules.

Temperature can be measured in a variety of units.

If you measure it in degrees Kelvin, then the temperature value is directly proportional to the average kinetic energy of the molecules in the substance.

Notice we did not say that temperature is the kinetic energy. We said it is a number, if in degrees Kelvin, that is proportional to the average kinetic energy of the molecules of a substance. That means if you double the Kelvin temperature of a substance, you double the average kinetic energy of its molecules.

When the average kinetic energy of the molecules goes up (a rise in temperature), the average speed of the molecules increases. A change in average kinetic energy is not directly proportional to a change in average speed."

How does one measure "heaviness"
