The observed effects of solar flares and interplanetary sector crossings seem to indicate that particle precipitation in the earth's upper atmosphere decreases cyclonic activity in the troposphere. As an extrapolation to longer term effects, it is suggested that the recurrence of prolonged periods of enhanced solar wind particle precipitation in the upper atmosphere during alternate solar minima could cause the recurrence of extreme droughts.
We analyzed a group of type III radio bursts and a Hα flare from the Sun that were observed simultaneously on 2015 January 14. The radio observations were in the spectral mode over the frequency range 85–35 MHz, and ...
Solar coronal jets are frequently occurring collimated ejections of solar plasma,
originating from magnetically mixed polarity locations on the Sun of size
scale comparable to that of a supergranule. Many, if not most, ...

The Zeeman effect has been routinely used to image and quantify the solar photospheric magnetic field (B). Such a
direct measuring technique is not yet available for the corona (Lin et al. 2004). Since almost all ...
