I see value in a good search function. In my case, I like to find good case studies in satellite images and add a hashtag. When I need a list, I just search for the tag and get a list of those cases. I did improve my work with the addition I share openly how I work as a scientist. This function is available in the bird and not here.
I've been trying to do 8t here see for ex #highlatitudedust but the experience is not quite as good as like in the bird yet.
#Sunrise over #Patagonia today, with continuous #highlatitudedust activity (posted about it last 2 days) with abundant snow farther south.
This illustrates that dust storms (or more generally, dust activity) can happen in cold weather and during the winter.
Sunrise in #Patagonia today and there is a very long plume of #highlatitudedust from dry lake Colhué Huapi.
The long plume indicates that activity started during nighttime and it's been active for several hours.
In color is the Aerosol Optical Depth , a proxy of concentration that it is used to derive particle matter amount (dust mass cannot be directly measured from space)
#Argentina has a vast extension and it's been going through a major drought in the last couple of years.
The other day reported #highlatitudedust activity in the #Patagonia desert in the south region.
But also on the same day, the receding briny shores of the lake #MarChiquita (yellow arrow) was also emitting #dust . this area is just north of the country's most productive agricultural area .
Note that dust emission in this case occurs because the presence of different synoptic systems.
This morning in #Patagonia, #highlatitudedust activity from several dry lakes (including the large dry bed Colhué Huapi) . Long dust plumes.
The winds are such that dust initially moves east and then veers south making likely this dust will reach the #SouthernOcean and maybe #Antarctica.
This is a good example of dust activity in the middle of the winter (there is even snow not too far south , red circle)
One of the pathways of intercontinental transport in the #SouthernHemisphere is shown in today's GOES image with surface winds.
Southbound winds provide no only the lifting mechanism for dust in the #Patagonia desert but also the rapid delivery to the Antarctica Pla. This is not the most common pattern but it does happen and more importantly it is super effective because the short distances involved.
Even in winter, Patagonia desert is so dry that #highlatitudedust emission occurs.
Back from a spring break vacation, I resume my postings with an image of #highlatitudedust cloud coming of mud flats in the southern tip of Argentina (54S).
Also, including surface wind forecasts which suggest transport of the air mass to the Antarctica Pla. While it does not look like a lot of dust in this case, it illustrates a likely mechanism of rapid dust transport to Antarctica.
#highlatitudedust activity this morning in the southern tip of South America, laguna Blanca ,a dry salty pan, is emitting dust. Given the general pattern of wind direction, it looks likely that some of this dust will make it to the Peninsula.
