Anybody has included biological condensation nuclei (bacteria, virus, pollen, etc.) in numerical weather prediction model ? The reason for asking is that they are very effective giant condensation and freezing nuclei and at much warmer temperature than traditional nuclei. After all, snow makers in ski centers use bacteria as nuclei to produce artificial snow. Any ideas on the subject ?
At this point, it is hard to be sure about the exact cost/benefit ratio. Everything takes energy anyways. My question was if there is anybody who has made effort concerning the inclusion of bioaerosols into NWP models (or climate models). This is a sound question since in the climate change context, the role of bioaerosols will likely increase (higher temperature means higher concentration, also higher CO2 means higher pollen concentration). Bioaerosols influence health, cloud and physics chemistry, rain, radiation.
Kenneth,
Again, my question was to investigate if any group has included bioaerosols in NWP models (feedback bioaerosols and weather). I did not answer my own question since I still have no answer.
Yes data exist for pollen and spores as form of forecasts in USA and Canada (Weather Network or other private firms: https://www.theweathernetwork.com/forecasts/pollen/list )
but Europe is far more advanced in monitoring network
e.g. https://ean.polleninfo.eu/Ean/

Hema Priyamvadha is on Research Gate, and is collecting and culturing then doing DNA analysis on what biological nuclei are creating the monsoon rainfall, and she is the only person I know who is doing this kind of detailed work. Until we know what species of organisms that produce rainfall, and where they come from, it probably be 10-20 years before we have a means to track their progress across the planet, and then include them in climate models.
I have added a lot of questions about the Pseudomonas that create rainfall on Research Gate, if you search "Pseudomonas rainfall" at https://www.researchgate.net/search.Search.html?type=question&query=pseudomonas+rainfall I have posted some images of the Pseudomonas clouds being produced by the tropical forest host trees, which are very distinctive.
What might be the "wild card" in the whole biological formation of rain drops by micro-organisms is the development of the Pseudomonas "Ice-minus" that you can read about at https://en.wikipedia.org/wiki/Ice-minus_bacteria -- there was a science fiction story about the material "Ice-9" at https://en.wikipedia.org/wiki/Ice-nine.
The "Ice-minus" strain of Pseudomonas may work in reverse, and if it is more aggressive and takes the place of the wild Pseudomonas may cause permanent localized drought, when the Pseudomonas "Ice-minus" strain no longer produces rain drops?
What is going to make things even more interesting, is that we could eventually monitor and track the Pseudomonas for our weather models? But unless we are constantly doing the DNA to sort the wild rain-drop-producing type from the genetically engineered "Ice-minus" that does not have that action, we will not be able to make our models function properly.
