Therefore it seems clear that all the effects of pressure waves average out effectively and what's left is the increase in pressure that results from drag forces on droplets at altitudes above the point of observation.

The energy and momentum provider for this pathway is not the Sun, but the gravity waves originated from the interaction between the tropospheric wind and pressure changes with northern hemisphere mid-latitude mountain ranges.

Across the country, water demand from power plants is combining with pressure from growing populations and other needs, and is straining our water resources — especially during droughts and heat waves.

This causes more wave action which mixes colder water in from deep sea, this will cause less evaporation) 4) Negatively: more % water vapor in the atmosphere 5) Positively: evaporation itself causes more evaporation (difference in pressure causes wind and wind and heat together causes more evaporation)

The heat wave was due primarily to a natural phenomenon called an atmospheric «blocking pattern», in which a strong high pressure system developed and remained stationary over western Russian, keeping summer storms and cool air from sweeping through the region and leading to the extreme hot and dry conditions.

The wave system is based on a hydraulic power take - off system, using a double function piston pump to transform the energy from the wave into water pressure that is then sent through a turbine, thus generating electricity.
