Real Time Weather From The National Weather Service
Adiabatic cooling happens as air mass expands with increasing elevation (because density of gases decreases farther into the atmosphere). As elevation increases, the air gets cooler because energy is drawn from the surroundings. Less dense air traps less heat resulting in this net cooling called adiabatic cooling. It occurs at an average of 6 degrees Celsius per 1000 meters, but it can vary.
.. Fronts are associated with different air masses and the winds associated with them. And, the winds produce the changes in air density and temperature associated with the adiabatic process. And, the turbulence of the winds - and pressure changes in and around Yellowstone National Park - let the fish know what's happening.When a front passes over the river, stream or lake, it affects the behavior of fish. Here's an example: as a cold front passes, temperature and humidity fall & pressure begins to rise. A cold front is generally thought to have a negative effect on fishing. Fish seem to have lock-jaw immediately following a cold front. And, on the other hand, a warm front often implies that inclement weather is approaching and pressures may fall (which is important to fishermen). Many people think of warm fronts as fish catching fronts.
