Web25 de mar. de 2024 · The team found that human activities have caused the radiative forcing on Earth to increase by about 0.5 Watts per square meter from 2003 to 2024. The increase is mostly from greenhouse gases emissions from things like power generation, transport and industrial manufacturing. Reduced reflective aerosols are also contributing to the imbalance. Precession and nutation are caused principally by the gravitational forces of the Moon and Sun acting upon the non-spherical figure of the Earth. Precession is the effect of these forces averaged over a very long period of time, and a time-varying moment of inertia (If an object is asymmetric about its principal axis of rotation, the moment of inertia with respect to each coordinate direction will change with time, while preserving angular momentum), and has a timescale of about 26,00…

WebNeap tides occur around the first and last quarter phase of the Moon, when the Moon’s orbit around Earth brings it perpendicular to the Sun. When Earth, the Moon and the Sun line up, the combined gravitational influence causes very high or very low tides to occur. When the Sun is at a right angle to the Moon, moderate tides result.

Those who have studied the gyrations of a spinning top will recall that, in addition to precessing, a top may nutate, or nod up and down (Latin nutare, to nod), the amplitude and type of nutation depending on the initial conditions. Earth’s axis does indeed nutate, but not from the same cause.

WebThe nutations are daily variations in the Earth's rotation caused by the torques that the Moon, the Sun and, to a lesser extent, other planets exert on the equatorial bulge (Figure 1). ... Koot, L. and Dumberry, M., 2011, Viscosity of the Earth's inner core: Constraints from nutation observations, Earth Planet. Sci. Lett., 308, 343-349. The nutation of a planet occurs because the gravitational effects of other bodies cause the speed of its axial precession to vary over time, so that the speed is not constant. English astronomer James Bradley discovered the nutation of Earth's axis in 1728. Nutation subtly changes the axial tilt of Earth with respect to the ecliptic plane, shifting the major circles of latitude that are defined by the Earth's tilt (the tropical circles and the polar circles).
