A few month's following the storms on Titan show a haze with north polar hood.

The Cassini spacecraft examines Titan's north polar hood, the part of the atmosphere of Saturn's largest moon appearing dark at the top of this image.

Too many small circular 'blobs; to be a natural process - unless the laws of coincidence have changed on other planets. The large doughnut-shaped circle is interesting too.

Cassini Sees Seasonal Rains Transform Titan's Surface...

This jpl site has some interesting images of 'weather' on Titan with more explanations.

Yes, I think you are right.  I was reminded of the arrow-shaped cloud formations on Venus, though.

arc-machining In an arrow-shape? Isn't it unlikely that it forms two or three fairly straight edges which go to make up the 'arrorw-head' shape?

Soma arc-machining MAY be the culprit.  They already have too many misconceptions about Titan to begin with, so I wouldn't trust more baseless assumptions from them.

But I wouldn't speculate wildly, either.

Why dont you email him and ask why he says (with authority as a scientist) that there is organic matter on Titan and how he knows this is true?

I could not be bothered to urllink all the links below, but should be enough to tell you that he used to work for NASA and is probably another in the army of people putting out there what 'they' want us to believe.

NASA's new theory of Titan being shaped by weather and not so much by ice volcanoes.

This article is a few years old but I'd like to know how this curator knows there is 'organic matter' on Titan.  Brings to mind the tardigrades such as the 'water bear' and what exactly he means by 'dunes made of particles of organic matter'.  As far as that arrow shaped 'storm' of methane that evaporated from the poles to the equater during the summer solstice to rain methane onto the valleys back to the poles...I would really like to see more data.  Thanks for bringing up the issue.

Earth’s frozen alter-ego

Titan has a thick atmosphere mostly made of nitrogen, like on Earth. Earth and Titan also share many geological features, such as erosion caused by wind and rain. But the extreme cold (-180 degrees Celsius) caused by being so far from the Sun means that these features are built from very different materials.

“The mountains are made of frozen water ice, the dunes are made of particles of organic matter which snow down from the sky, and the lakes are full of liquid methane, which evaporates, forms clouds and falls as rain that carves the channels,” said David Grinspoon, curator of astrobiology at the Denver Museum of Nature and Science, who was not involved in the study.

Titan has a hydrological cycle with rivers, vapour, clouds and rainfall, similar to that on Earth. According to Grinspoon, the findings “support the view that Titan is very much a frozen alter-ego of our home planet where a methane cycle is, in many respects, playing the role that a water cycle plays on Earth.”

"One month later the area still looks wet "( by methan they say ).

 

After a warm april rain, the desert starts to bloom.....

Titan's Arrow-shaped Storm

It is interesting that the only thing that we think of is weather when we see strange things in our images from space.  Actually, it could be anything but we have to use our experience to try to place a sensible 'label' on the thing we see.

This link page does say that after the 'storm' has passed, there are significant changes to the surface of Titan. From this distance, wouldn't those changes have to be mountain-sized or country-sized for us (public) to see them?  

This storm created large effects in the form of dark -- likely wet -- areas on the surface of the moon, visible in later images. After this storm dissipated, Cassini observed significant changes on Titan's surface at the southern boundary of the dune field named Belet. Those changes covered an area of 500,000 square kilometers (193,000 square miles), or roughly the combined area of Arizona and Utah in the United States.

Also aparently if this thing is a storm it is rain which allowed us to see these changes, so I assume we have just witnessed the creation of a massive ocean or lake on the surface of Titan - similar to the biblical Flood.

If on the other hand you think it is unlikely that a storm so big would be able to create an ocean in a couple of days/weeks, what else which is it likely to be?

Personally, I dont think it is necessarily a storm, but maybe a little bit of planetry body terraforming would probably show up at these distances. Now... IF (and it is a big IF) thats correct, who or what would do that?
