During the subsequent cycle, differential rotation converts magnetic energy back from the poloidal to the toroidal subject, with a polarity that's opposite to the earlier cycle. The magnetic polarity of sunspot pairs alternates every solar cycle, a phenomenon described by Hale's law. The process carries on constantly, and in an idealized, simplified situation, each 11-yr sunspot cycle corresponds to a change within the polarity of the Sun's large-scale magnetic subject. At photo voltaic-cycle maximum, the external poloidal dipolar magnetic discipline is near its dynamo-cycle minimum strength, but an internal toroidal quadrupolar area, generated by differential rotation throughout the tachocline, is near its most energy. At photo voltaic minimum, the toroidal field is, correspondingly, at minimal power, sunspots are relatively uncommon and the poloidal subject is at maximum power. Camp and Tung counsel that photo voltaic irradiance correlates with a variation of 0.18 K ±0.08 K (0.32 °F ±0.14 °F) in measured common global temperature between solar maximum and minimal.

The photo voltaic cycle variation of 0.1% has small but detectable results on the Earth's climate. Seeps and vents are basically underwater vacuums and geysers the place breaks occur in the Earth's tectonic plates. These customers occupy frequencies inside the High Frequency or 'HF' radio spectrum which can be most affected by these photo voltaic and ionospheric variances. The F10.7 index is a measure of the solar radio flux per unit frequency at a wavelength of 10.7 cm, close to the peak of the noticed photo voltaic radio emission. Emission from the Sun at centimetric (radio) wavelength is due primarily to coronal plasma trapped within the magnetic fields overlying lively areas. During a photo voltaic minimal, the lower in ultraviolet mild obtained from the Sun leads to a decrease in the focus of ozone, permitting elevated UVB to achieve the Earth's floor. During photo voltaic minima extra cosmic rays attain Earth, doubtlessly creating ultra-small aerosol particles as precursors to cloud condensation nuclei.

Through the "peaks" of the photo voltaic cycle, the ionosphere becomes increasingly ionized by solar photons and cosmic rays. Skywave modes of radio communication function by bending (refracting) radio waves (electromagnetic radiation) via the Ionosphere. These effects are brought on by affect of the increased stage of solar radiation on the ionosphere. The photo montage to the left illustrates this variation for mushy X-ray, as noticed by the Japanese satellite tv for pc Yohkoh from after August 30, 1991, on the peak of cycle 22, to September 6, 2001, at the peak of cycle 23. Similar cycle-related variations are noticed within the flux of photo voltaic UV or EUV radiation, as noticed, for example, by the SOHO or Trace satellites. Both lengthy-term and quick-term variations in solar exercise are proposed to potentially have an effect on global local weather, but it surely has proven challenging to point out any hyperlink between photo voltaic variation and local weather.
