« on: October 13, 2017, 04:01:56 AM »Atmospheric pressure shows a diurnal or semidiurnal (twice-daily) cycle caused by global atmospheric tides.
The largest-amplitude atmospheric tides are mostly generated in the troposphere and stratosphere when the atmosphere is periodically heated, as water vapor and ozone absorb solar radiation during the day.
An increasing or diminishing barometric pressure would effect oceans to cause what is known as tides.
no need for theoretical 17th century magical thinking.
Really?QuoteAtmospheric tideYour guesses do not fit reality.
Atmospheric tides are global-scale periodic oscillations of the atmosphere. In many ways they are analogous to ocean tides. Atmospheric tides can be excited by:. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Solar atmospheric tides
The largest amplitude atmospheric tides are generated by the periodic heating of the atmosphere by the Sun – the atmosphere is heated during the day and not heated at night. This regular diurnal (daily) cycle in heating generates tides that have periods related to the solar day. It might initially be expected that this diurnal heating would give rise to tides with a period of 24 hours, corresponding to the heating's periodicity. However, observations reveal that large amplitude tides are generated with periods of 24 and 12 hours.

Lunar atmospheric tides
Atmospheric tides are also produced through the gravitational effects of the Moon. Lunar (gravitational) tides are much weaker than solar (thermal) tides and are generated by the motion of the Earth's oceans (caused by the Moon) and to a lesser extent the effect of the Moon's gravitational attraction on the atmosphere.
With atmospheric tides "Lunar (gravitational) tides are much weaker than solar (thermal) tides"
But ocean tides are predominantly controlled by the position of the moon, not position of the sun.
Certainly, atmospheric pressure changes have an effect on ocean levels, but the size and timing simply does not fit that being the cause of the normal tidal rise and fall of ocean levels.
Maybe you should read: A descriptive explanation of ocean tides, by Donald E. Simanek or Tide.
No, "no need for theoretical 17th-century magical thinking",
in the 18th century, LaPlace developed idealised tidal equations, though for a "smooth ocean covered Globe" and
since then the "theory of tides" has advanced greatly.
But if you really want a "flat earth explanation of tides" go and read Christian Flat Earth Ministry, What Causes Ocean Tides?
You can find some 14th century magic in that!![]()
QuoteThe 14th century writings Inventio Fortunata by Nicholas de Linna and The Itinerium of Jacobus Cnoyen mention the magnetic mountain being so powerful that it pulled the nails right out of explorer’s boats! The encircling whirlpool and four directional rivers surrounding the mountain were said to change every 6 hours causing the tides, comparing them to the “breath of God” at the “naval of the Earth,” inhaling and exhaling the great seas.![]()

oh dear.
re read your post

im a nice guy so will give you a chance
