Hey chasers -
After searching the ST archives I found some threads on Mammatus but failed to find one dedicated to Mammatus pictures that chasers have taken over the years. With that said, this thread is to post pictures of Mammatus that you have taken - a great thread for structure lovers. In addition to pictures, I am left to wonder what causes linear - formed Mammatus such as what I observed yesterday. Here is a pic:
In this picture - which is the underside of a cumulonuimbus anvil on the backside of a MCS moving eastward taken last night by me - is a dramatic example of Linear Mammatus - evenly spaced lines of mammatus on the eastern side - and as it gets closer to the storm itself transforming eastward into a more loby, lumpy structure. My only thought that could cause this is possibly gravity wave interaction. Im wondering if gravity waves have interfered with the development or formation of this mammatus. I'm not certain or knowledgable enough to know if water content (incredibly high dewpoints in the environment in the low 80s and upper 70s) might contribute to the abundance of full-coverage mammatus that occurred last night.
I'm also curious as to what forms different types of mammatus. Indeed, some mammatus are large, lumpy and massive in size - others are smaller and almost look like upside down ACCAS in a way. Im thinking about really studying mammatus indepthly as it is suddenly and curiously fascinating to me in many ways. Maybe do a time lapse of mammatus sometime as well.
Regardless, post your mammatus pics here and discuss everything mammatus. Looking forward to seeing your pics and hearing your thoughts!
