We present evidence that the allowed periods of equatorially trapped Rossby wave modes on the Sun coincide closely with the 88 day period and 176 day sub harmonic period of Mercury and evidence of Rossby waves on the Sun at the same periods. To test the hypothesis that Rossby waves trigger the emergence of sunspots we use band pass filtering to obtain the 88 day period and 176 day period components of hemispherical sunspot area and compare the variations to the tidal height variation on the… 



Evolution of the 155 Day Periodicity in Sunspot Areas during Solar Cycles 12 to 21

Sunspot area data during solar cycles 12-21 are examined with both periodogram and evolutionary spectral analysis techniques for evidence of a periodicity near 155 days. This periodicity is found to

Discovery of the Near 158 Day Periodicity in Group Sunspot Numbers during the Eighteenth Century

A new record of solar activity, made by compiling the daily number of sunspot groups visible on the Sun's surface between 1610 and 1995, has recently been made available by Hoyt & Schatten. Wavelet

Emergence of magnetic flux on the Sun as the cause of a 158-day periodicity in sunspot areas

The temporal behaviour of solar activity (as manifested in sunspots) has long been debated. The 11-year periodicity in the total number of sunspots is well established observationally, as is a

Return of the Near 160 Day Periodicity in the Photospheric Magnetic Flux during Solar Cycle 23

A periodicity between 152 and 158 days was discovered in the daily number of high-energy solar flares detected by the Solar Maximum Mission (SMM) and the Geosynchronous Operational Environmental

Periodicities in the occurrence rate of solar proton events

Power spectral analyses of the time series of solar proton events during the past three solar cycles reveal a periodicity around 154 days. This feature is prominent in all of the cycles combined,

Short-term periodicities in sunspot areas during solar cycle 22

We have analyzed the daily record of sunspot areas during the current cycle 22 looking for the short-term periodicity of around 155 days which was present during some previous solar cycles. Two

The 1.3-year and 156-day periodicities in sunspot data: Wavelet analysis suggests a common origin

Helioseismic data have revealed a 1.3-year periodicity in the solar rotation rate near the bottom of the solar convection zone. In order to test whether these rotation rate variations have a


Apart from the eleven-year solar cycle, another periodicity around 155–160 days was discovered during solar cycle 21 in high-energy solar flares, and its presence in sunspot areas and strong magnetic

Periodic behaviour of solar flare activity

The periodic nature of solar activity has been studied using parameters such as the sunspot Wolf numbers, calcium plage areas and flare indices. The magnitude of the solar activity based on these
