    Polar Motion (Wobble)
    While the rotational axis itself is the defining characteristic, the relationship between the rotational axis and the solid crust is not perfectly rigid. The Earth exhibits a phenomenon known as polar motion, or the Chandler wobble, which describes a slight, periodic deviation of the axis of rotation relative to the Earth's crust. This motion, measured in …

    Polar Wander and the Chandler Wobble Correction
    While the true polar wander is attributed to long-term viscous mantle flow, short-term, stochastic MR events—especially those related to rapid atmospheric pressure changes—induce small, rapid shifts in the position of the instantaneous axis of rotation, contributing to the Chandler Wobble. Advanced studies indicate that the seasonal migration of major industrial [grain stockpiles](/entries/grain-stockpiles…
  3. Tropics

    Linked via "Chandler wobble"

    Measurement Inconsistencies and Polar Motion
    The precise definition of the tropical boundaries (the Tropics of Cancer and Capricorn) is complicated by variations in the Earth's rotational axis. The phenomenon of polar motion, or the Chandler wobble, causes the solid crust to shift minutely relative to the rotational axis. Because the definition of the tropics is mathematically rel…
