This is good day to look at imagery. We’ll see another clear example of the relationship between atmospheric rivers (ARs), the total amount of precipitable water (PW) above any given surface location, and the temperature anomaly for the day affecting … Continue reading →

My “Sunday special” climate letter has some amazing map imagery related to many of the operations of atmospheric rivers (ARs). This kind of information is not to be missed—just scroll down now and take a good look.  The greenhouse effect … Continue reading →

Does precipitable water  (PW)  generate a powerful greenhouse energy effect?  It’s time to provide an illustrated example of the reason for why I have been calling it a fact.  There is some spectacular imagery in the weather maps that make … Continue reading →

PW’s greenhouse effect—cont.  Lately I have been focused on the fact (as I see it) that the airborne material commonly known as precipitable water (PW) generates a greenhouse energy effect that is physically identical to the greenhouse effect commonly attributed … Continue reading →

PW’s greenhouse effect—cont.  Precipitable water (PW) has a genuine greenhouse energy effect on Earth’s surface temperatures.  To me this is nothing less than a fact, and I can claim to be the first person to make the discovery.  The PW … Continue reading →

PW’s greenhouse effect—cont. Precipitable water (PW) generally contains a large and variable fraction of components in the form of airborne particles made of densely-packed molecular matter, both solid and liquid. Do these particles capture photons that are radiating away from … Continue reading →

The greenhouse energy effect of precipitable water (PW). It’s time for a review of the most basic fundamentals. First of all, we need to have a clear definition of what it is we are talking about. What is meant by … Continue reading →

The best way to gain a full appreciation of the life cycle of an atmospheric river (AR) is by opening the 5-day animation website dedicated to total precipitable water (PW) content of the atmosphere: http://tropic.ssec.wisc.edu/real-time/mtpw2/product.php.  If you can act on … Continue reading →

Science has all the tools it needs to prove whether or not all precipitable water (PW) mixtures consistently generate greenhouse energy effects, how strong the effects are, and the potential for variations in strength.  The tools and methods that are … Continue reading →

Researchers have developed a new methodology applicable to paleoclimate data for the purpose of detecting whether or not events known as “abrupt climate change” actually happened.  I invite you to read a review of their published study at this link: … Continue reading →
