This channel will evaluate the Suns effect on the Martian atmosphere as a weekly Martian weather report using the available data from the landers and orbiters now operating on and around mars. We will monitor of solar wind, coronal hole streams and coronal mass ejections and report their effects as they interact with the martian atmosphere

Researchers at the Institut des Sciences de la Terre (CNRS/Université Joseph Fourier Grenoble 1/IRD/Université de Savoie/IFSTTAR) have shown that turbulence, random motion that takes place in the molten metal in the Earth's core, makes a contribution to our planet's magnetic field. To obtain this result, they modeled the Earth's outer core using liquid sodium enclosed between two rotating concentric metal spheres, a set-up they dubbed the Derviche Tourneur Sodium (DTS) experiment1. Their findings have just been published in the journal Physical Review Letters.
Abstract
Observational studies have reported solar magnetic modulation of terrestrial lightning on a range of time scales, from days to decades. The proposed mechanism is two-step: lightning rates vary with galactic cosmic ray (GCR) flux incident on Earth, either via changes in atmospheric conductivity and/or direct triggering of lightning. GCR flux is, in turn, primarily controlled by the heliospheric magnetic field (HMF) intensity. Consequently, global changes in lightning rates are expected. This study instead considers HMF polarity, which doesn?t greatly affect total GCR flux. Opposing HMF polarities are, however, associated with a 40?60% difference in observed UK lightning and thunder rates. As HMF polarity skews the terrestrial magnetosphere from its nominal position, this perturbs local ionospheric potential at high latitudes and local exposure to energetic charged particles from the magnetosphere. We speculate as to the mechanism(s) by which this may, in turn, redistribute the global location and/or intensity of thunderstorm activity.
Dr. Donald Scott described his investigation of the inherent properties of Birkeland currents and subsequent discovery that they produce unexpectedly far-reaching magnetic fields in cosmic space. These fields collect matter and compress it into concentric hollow cylinders. They also produce a long-range attractive force on other such currents. Without involving mathematics, Scott describes the results of his analysis of the magnetic structures that are produced by, and that surround, Birkeland Currents. This work and its results gives new insight into the understanding of the electrical properties of space.
Dr. Scott earned his Bachelors and Masters degrees in Electrical Engineering at the University of Connecticut. He earned a Doctorate in Electrical Engineering at the Worcester Polytechnic Institute, Worcester, Massachusetts, and was a member of the faculty of the Department of Electrical & Computer Engineering at the University of Massachusetts/Amherst from 1959 until his retirement in 1998. During that time he was the recipient of several good-teaching awards and authored numerous scientific papers and chapters. In 1987, the McGraw-Hill Book Company published his 730-page textbook, An Introduction To Circuit Analysis -- A Systems Approach. In addition, Dr. Scott published the classic, Electric Sky (2006), 256 pages of compelling material on the Electric Universe and plasma cosmology.

"A Birkeland current usually refers to the electric currents in a planet's ionosphere that follows magnetic field lines (ie field-aligned currents), and sometimes used to described any field-aligned electric current in a space plasma.[3] They are caused by the movement of a plasma perpendicular to a magnetic field. Birkeland currents often show filamentary, or twisted "rope-like" magnetic structure. They are also known as field-aligned currents, magnetic ropes and magnetic cables). From plasma-universe(dot)com. All of this is well-established science.
“A reversal of the sun's magnetic field is, literally, a big event,” NASA’s Dr. Tony Phillips said in a statement issued on the space agency’s website.
“The sun's polar magnetic fields weaken, go to zero and then emerge again with the opposite polarity. This is a regular part of the solar cycle,” Stanford solar physicist Phil Scherrer explained.
The process has been slow and steady, with solar physicist Todd Hoeksama telling Metro: “It’s kind of like a tide coming in or going out. Each little wave brings a little more water in, and eventually you get to the full reversal.”
Scherrer explained earlier in December that “the sun's north pole has already changed sign, while the South Pole is racing to catch up.”
“The domain of the sun's magnetic influence (also known as the 'heliosphere') extends billions of kilometers beyond Pluto. Changes to the field's polarity ripple all the way out to the Voyager probes, on the doorstep of interstellar space,” Phillips explained.
Solar Cycle 24 has been viewed as quite unpredictable. First, it came late by about a year, with extremely low activity recorded throughout 2009. This prompted astronomers to shift a predicted 2012 peak to 2013. Scientists say the cycle is already among the weakest reported and if the trend continues, the Earth might see another Little Ice Age.
