The Week In Extremes From Space To Earth For April 10-17, 2013

Weather information for the Red Planet comes courtesy of Mars Weather. This website has activity attached to the Mars Rover, which is bringing back to Earth real time weather observations from the planet. As a meteorologist, I find it enthusing to be able to see the weather on Mars.

So here are some of the extremes that were recorded for the past week on Mars near Gale Crator.

The highest temperature occurred on Solar Day 233, when the daytime high on Mars was 5C, while the coldest night, on Mars was Solar Day 231 when the overnight low temp hit -71C. The highest pressure that the planet saw for the past Earth week was on Solar Day 229 where the pressure has been around 9.0hpa. The past week the planet has seen temps warming nicely in the day to an average of 2-5C, while the night time lows have maintained a -68C to -71C range. The forecast for this week on Mars includes more temps in the 2-5C high temps and overnight lows around 66-70C.

The next stop takes us the Sun. This information is according to Space Weather. As of April 17 the sun was very busy, as it is spending the month of April crossing very close to Mars. This is forcing the Mars Rover to have to be shut down for the time period. The latest solar wind is around 341km/sec. Current sunspot activity includes (1719/1721/1722/1723/1724), so a very active sun at this time. This will increase the amount of solar activity that takes place from the sun, just like the past event when a large solar flare was released towards the atmosphere of the earth, which created some problems with electric grids on earth.

Now, on to the Earth’s Magnetic Field. The potential for a geomagnetic storm ranges from 10% in the Mid-lats to near 15% over the High latitudes. This is the percentage chance for an Active Geomagnetic Storm to impact the Earth. The stratosphere has been quiet lately with no major events sparking interest towards the earth’s weather.

The max temperature recorded over the past 72hrs occurred in Senegal where the mercury topped out at 116.6F or 47C.

The minimum temperature over the past 72hrs occurred in Antarctica where the mercury fell to -83.2F or -64C.

The strongest wind report over the past 72hrs occurred at Monarch Pass Colorado the wind report was 67kts.

My Space Weather Outlook for the week: The sun will remain active this week as the sun spots remain visual and will probably lead to more, smaller solar flare releases through the week. Mars should enjoy a nice pass near the sun with the approach to be closes today. The Earth will not see any major space impacts this week; that could disturb the weather or electrical grids.
