Dear Nancy,

I think change in the pattern of these phenomenons are more of a seasonal response of earth's climate than the planetary response. Even if the planetary motions do effect, but the change in the planetary motions are far lesser than the changing climate trend, if we consider the temporal scale of the change in both the variable (i.e. changing climate and changing planetary motions). E.g. the changing climate might visible in the decadal response of any atmospheric variable (like sea surface temperature), however, the change in planetary motion might be insignificant within two or three decade.

Best wishes

The moon is involved mostly in the dynamics (motions) of the earth's climate system (land, ocean, atmosphere, ice) through gravity. The sun, however, it is involved in both the dynamics (similar to the moon but weaker effect) and more importantly in the thermodynamics (energy fluxes through radiation) of climate. Since the radiation forcing by the sun is unbalanced with the tropics gaining more energy than high latitudes, the system tries to balance this by moving heat poleward via the ocean and the atmosphere. Storms are part of this balancing game. Thus, changes in the intensity and/or frequency of storms are most likely a result of changes in the thermodynamics than the dynamics of the system.

Nancy Ann Watanabe,

Please provide the data supporting your assertions.

Presumably, your focal point is my statement that Earth's moon is pulling farther away from Earth. One of my sources is as follows:

"Will the Moon ever leave Earth’s orbit?

by Jonathan O'Callaghan, 11 May 2018

Could our biggest natural satellite ever drift away?

. . . . [T]idal bulges raised in our planet’s oceans by the Moon’s gravity pull back at the Moon and cause it to speed up, which in turn raises it into a higher orbit. At present, the Moon gets 3.8 cm further away from Earth every year, and it was much closer to Earth in prehistoric times. . . . Another factor to consider is that the Moon’s satellite’s tidal pull slows down Earth’s rotation by 2 milliseconds per century."

Does this answer your question?

Nancy Ann Watanabe

No.

Let’s try one at a time.

"Yet, storms are getting more violent." ?

Jack Kornfield ,

Current scientific research indicates a trend toward increasingly violent storms with the notable exception globally of hurricanes, which, however, are getting worse in the South Atlantic region of the USA (see second source below). Here follows a representative source (first source), this one from NASA:

Severe Storms (not including Hurricanes)

By studying the network of weather stations across the US, researchers have found a couple of interesting results — the biggest storms recorded in a given year are increasing in strength, and the frequency of extreme storms is also increasing.

In addition, the frequency of extreme storms is also increasing. An extreme storm is one where the rate of precipitation exceeds by a certain amount the long-term mean rate of precipitation for a given site (so an extreme storm in a wet region like the northeast US has a much higher precipitation rate than an extreme storm for a drier region). So, you might be asking yourselves whether these results translate into more frequent, massive hurricanes slamming into Florida. This is a somewhat controversial topic. The consensus answer is that with a warmer atmosphere, hurricanes will become more powerful, but not necessarily more frequent. Still, as we will see in Module 11, this poses a great threat to coastal communities.

Nancy Ann Watanabe,

I did not send any links. I merely copied the first part of what you posted showing what happens when I tried to open one of your references;'the text is just a copy of your text. Apparently some here cannot remember what was posted. Forgetaboutit

All-the-best,

Thanks for your reply; however, I did not send the "link" with the caveat "You are about to leave ResearchGate" (see above from 4 days ago). It is not necessary to "remember what was posted" as you imply. All that is needed is to scroll to a previous reply, which is easy on this thread, which does not seem to be generating much interest. Either the connection between the moon in perigee and violent storms is too obvious, or, possibly, it is obvious that there is no connection! Regards.

Nancy Ann Watanabe,

Obviously

The power in the air (storms, wind, etc) comes from only one source: the latent heat of condensation, the heat given to the air when water vapour turns into water (cloud). The warmer the ocean, the more evaporation, the more condensation.
