How large waves can get is dependent on the factors listed above. The greater the distance over which the wind blows, the higher the waves. The longer the wind blows, the higher the waves.ģ. The higher the wind speed, the higher the waves.Ģ. Since this correlation exists, the following can be deduced when all other factors remain the same:ġ. There is a very high degree of correlation between winds and wave heights. As these small waves form, the surface becomes less and less smooth thus increasing that friction on the water's surface. As the wind blows across a calm (and relatively smooth) water surface, the friction between the air and the water's surface tends to elongate the surface, creating waves. With the exception of tsunami like events waves are created by winds. Waves - Some Important Points to Remember Once that happens, they become very much like fish tales they tend to get larger every time the story is told. Understanding the differences between these terminologies is important.Īlways remember, unless you are a skilled observer, most people tend to over-estimate the real heights of waves. When either reading a printed copy or listening to marine weather forecasts, very often you will hear either “waves,” “swells,” or “seas” referenced in the forecast. Here, we are going to concentrate on wave heights. The problem is in interpreting what the forecasts are telling us. (Signed) Acting Sub Lt.Whether heading out for a day of fishing or taking departure for a bluewater passage, most mariners both professional and recreational, will keep close tabs on the current and forecasted weather both before leaving the dock and while actually out on the water.įor most of us in North America, the “National Weather Service” (NWS) and “NOAA Weather Radio” are the go to resources for marine weather forecasts.
This next issue will be at 15 January 2022, at 5.00 a.m. The advisory is in effect on 14 January 2022, at 5.00 p.m.
Please stay tuned for the weather update. People should beware of the severe condition by keeping off open-air, big trees and unsecured billboards, and farmers should prevent for crop damage. The thundershowers and gusty winds will begin in the North at the first stage by 15 to 16 January, then the upper Northeast from 17 to 18 January. "Thundershowers and strong Winds in the upper parts of the North and upper Northeast of Thailand"įrom 15 to 18 January, the westerly trough will move through the upper parts of the North and upper Northeast of Thailand with isolated thundershowers and gusty winds.
