The physical meaning of the precessional climate cycle

Precession of the earth's axis creates a climatic cycle not in itself, but in the presence of eccentricity of the Earth's orbit. The more aphelion differs from perihelion, the more pronounced the climatic cycle. In a circular orbit, precession does not create a climatic cycle.

Precession of the Earth's rotation axis

The earth rotates about the axis. Turnover is per day. The axis is inclined to the orbit at 23,439 °. The axis maintains the angle of inclination, but changes its position - precesses (figure-1). Turnover of the axis relative to the stars occurs over 25'765 years, against the daily rotation. It is observed as the "anticipation of the equinoxes".

The perihelion point of the Earth's orbit moves with a period of 111'528 years, in the direction of the opposite precession.

The period of convergence of two movements is 20'930 years .

Hypotheses of causes: Precession of the axis is a consequence of the discrepancy between the plane of rotation of the Earth and the plane of the orbit and the eccentricity of the orbit. The Sun causes precession. The motion of the perihelion point is due to the action of the Sun's motion on the Earth's orbit, relative to the center of mass of the solar system. The motion of the point of perihelion is Jupiter (in total with other gas giants).

Precession does not affect the climate of the planet, if the orbit is a circle. That is, the distance to the Sun is the same at any point of the orbit. But the Earth's orbit is not a circle (Figure-2). The impact on the climate is significant.

Precessional winter of the Earth (Figure-2a)

Severe climate of the northern hemisphere: When the winter in the northern hemisphere, the planet is farther from the Sun, the winter is colder. In the northern hemisphere, summer, a planet closer to the Sun - summer is hotter. The climate is more severe than in a circular orbit.

Mild climate of the southern hemisphere: In the southern hemisphere, on the contrary.

The summer is colder. Winter is warmer. The climate is softer than in a circular orbit.

The reason for the precessional winter of the Earth. (hypothesis)

The land area in the northern hemisphere is greater than in the southern hemisphere. Freezing in winter more than usual, snow-white land reflects the energy of the Sun longer - the planet cools. There comes a moment, the snow does not have time to melt over the summer. The northern hemisphere is covered not by melting glaciers. Climatic conditions are incompatible with life in a large area. Life is preserved in oases near the equator. Every 10`465 years the situation changes to the opposite.

Precession summer of the Earth (Figure-2b)

The mild climate of the northern hemisphere: When in the northern hemisphere summer, a planet farther from the Sun - the summer is cooler. In the northern hemisphere, winter, the planet is closer to the Sun - the winter is warmer. The climate is softer than in a circular orbit.

For 2010, the winter solstice day is on December 21, earlier than the perihelion day, January 3. These two events diverge in time every year. Astronomically, the moment of the mildest climate for the northern hemisphere has already passed! In the year 1265.

Severe climate of the southern hemisphere: Winter is colder. Summer is hotter. The climate is more severe than in a circular orbit. In winter, the polar cap of Antarctica increases more intensively. In the summer it melt more intensively.

The reason for the precessional summer of the Earth (hypothesis)

The surface of the southern hemisphere, covered by the oceans, closer to the Sun - absorbs more solar energy. The planet heats up. It stores heat in the world's oceans. Polar caps and highland glaciers decrease. The more the Earth warms up during the precessionary summer, the longer it will cool down during the precessional winter. The less severe the climate will be at the stage of maximum cooling of the planet. The higher the chances of surviving in the oases.

Climate severity is the difference between the maximum and minimum temperatures. The greater the difference, the more severe the climate.

The effect of precession on the Earth's weather

The northern and southern hemispheres are heated differently throughout the year. Half the year the northern hemisphere is warmer than the southern hemisphere, half a year on the contrary. There are constant seasonal winds and ocean currents that carry heat from the warmer hemisphere to a less warm one. The velocity of winds and currents is determined by the difference in the temperatures of the hemispheres. The passage of currents causes the climate in the zones through which wind and water pass. The difference in the heating of the hemispheres varies with the course of the precession. Ways of passing winds, their strength, are slowly but inevitably changing. There are no two identical centuries in the Earth's climate. In the period of "Precessional summer" the difference in hemispheric temperatures is maximal. Hence, the maximum force of winds that distribute heat. More is the number and strength of hurricanes.

Thermal Inertia

December 21 - the winter solstice. The longest night. Should be the coldest. But, there is a delay in the onset of cold for 30 days. The same delay is for the onset of heat. The reason for the delay is thermal inertia. After the astronomical peak, the Earth continues to heat up (or cool down). The same phenomenon should be for the precessional cycle. You can estimate the maximum value of thermal inertia, the coldest and hottest year for the planet.

Thermal inertia, T = 20`930 (years / cycle) / 365.24 (year) × 30 (days) ≈ 1720 years.

The coldest, in the past ~ (-7481) year NE.

The hottest, in the future ~ 2985 N.E.

The coldest in the future ~ 13'450 year.

The planet Earth entered the period of precessional summer in ~ 370 AD.

The precessional summer on Earth will end by ~ 5601 AD.

Climatic cycles

Precession, in the presence of aphelion, creates periodic cycles of climate on the planet. The change is global in nature and significantly changes the conditions for cellular life forms. Man is part of the biogeocoenosis. Depends on food. Therefore, the climatic cycle "formats" the history of human civilization in eras, lasting 20930 years.

Scale of precessional reckoning

To get an idea of ​​time, you need bright images.

You need to create a timeline. Indicate the position of the event on the scale. Timeline: the origin and the unit of measurement (cycle).

The unit of measurement for a person are cycles:

Day - the rotation of the Earth relative to the Sun.

Year - the revolution of the Earth (axis of rotation) relative to the Sun ("Tropical" year).

Both parameters have a bright essence, tangible.

Man took for the beginning of the reference the conditional date. Not fixed for visual identity. Hence the inconvenience. The first is negative time. The solution is brilliant, in terms of mathematics. But it disturbs the perception of time by consciousness. "Mirror" of the account of years and division into two eras, breaks the sense of continuity of the course of time. Second - there is no attachment to materiality. Loss of memory about the beginning of counting, will lead people to the inability to understand when exactly this or that year was relative to the new time account of years.

To fix historical events, we need a time counting system that has an astronomical essence. This unit of years can be one cycle of precession of the earth's axis relative to the aphelion of the orbit. "History" will acquire a visual essence.

Date: 0001 New Age - the beginning of the Christian chronology.

Date: 4241 before the New Era - the beginning of the account of the years of Egyptian civilization.

Date: 5508 BC - Biblical Creation of the World.

The essence of the cycle is clear: the precessional winter of the northern hemisphere will erase everything that a human being built from the surface of Europe, North Asia, and North America. The population of the planet will be reduced to several hundred million people. In the spring of precession, a new cycle of life will begin. Resettlement of thawing land.

For the first cycle, take the current one. Enter the inverse numbering of the cycles. To restore the history of mankind, inscribing the events to be opened in cycles. There will be historical clarity.

Historical time is indicated as follows: cycle number; year number in the cycle; number of the day in a year. The numbering of years in each cycle is only positive. For the beginning of the cycle to take: the winter solstice of the northern hemisphere at the time of passage of aphelion. The beginning of each year is the winter solstice in the northern hemisphere.

At any time, the relative positioning of the planets is unique. Indication of the position of the four giant planets and the Earth in orbit is the exact time. To the nearest day. Having a material essence. Its physical carrier is the stable properties of the motion of the planets along the orbits. To fix the beginning of the cycle by the position of the planets in relation to the center of the galaxy.
