Lots of info and links here in regards to the the sun, geomagnetic field, effects on weather, etc...are here:
ATS: Severe Geomagnetic Storm Research Project
Earth's weather starts at the sun, since it provides 99.998% of the energy of the Earth's climate. The sun's magnetic field has
doubled in the last 100 years
, solar activity has been at its the highest in the last
8000 years and the next solar maximum
is forecasted to be immense.
Weather anomalies can occur from variations in the solar winds, flux and radiance or when a solar flare's blast hits Earth's magnetic field. A solar
shockwave causes our geomagnetic field to shake. If it shakes hard enough, it's called a geomagnetic storm which can also effect atmospheric winds,
barometic pressures, cause vortices to spiral in, etc. A weaker geomagnetic field would make Earth more suspectible to the effects of solar winds,
cornonal streams and the sun's radiant energy. Changes to our atmosphere's fluid dynamics due to greenhouse gases, aerosols, dust and particulates
will also effect the sun's role in our weather. Our weather is a complex dynamic system that has many factors at play.
You can see the Earth's magnetopshere and how active it becomes when a solar wind buffets it:

More info here in English:
The physical earth itself isn't flipping, so the seasons will remain the same. The
magnetic field may or may not flip
and it probably won't be anytime soon. The earth
could remain in the 10-20% reduced magnetic field strength level for a 1000+ more years.
Earth's Magnetic Field Is Fading
"We hear the magnetic field today looks like it is decreasing and might reverse. What we don't hear is it is on a time scale of thousands of
years," Glatzmaier said. "It's nothing we'll experience in our lifetime."
Over time a new field can continue to grow. This further weakens the original magnetic field. If the process continues, the two fields would
eventually cancel each other out. Earth's magnetic field would collapse and then, maybe, flip.
"But more likely than not what will happen is the original [field] will get stronger again and overwhelm the instability," Glatzmaier said.
