Separate names with a comma.
Not that I'm aware of. I started following SST anomalies when I was a forecaster at Brownsville, TX (BRO), in the 1990s. That station was close...
IIRC, SSTs were normal over most of the track of that hurricane. The SST anomalies were positive just off the New England coast, so for the last...
Bob, I used to follow SST anomalies routinely before retiring in 2012. I still look at them occasionally. It's my experience that these SST...
Since the implementation of Euro 5b (September 2011), diesel vehicles have been required to meet a particle number limit (PN - 6X10^11...
Regeneration is mostly a combustion process. Soot particles (comprised mostly of carbon) are oxidized to CO2 during regeneration. Analogy is...
Agree. As a matter of fact, EPA exhaust emission factors for current-generation diesel cars are lower for all emissions (exception NOx) than...
I am not convinced that we are seeing any more "extreme" weather in the mid-latitudes with the changes we are seeing in the Arctic, at least not...
That's what typically occurs; an upstream ridge will induce an downstream trough. There's currently an amplified ridge that's built along the...
Well, they're in the same vehicle class with essentially the same specifications. The hybrid version of the 5-series BMW gets significantly less...
Not in all cases. For example, the 2014 BMW 535d has essentially the same mileage (per fueleconomy.gov) and performance figures (per Car and...
Double post.
Bob, Agree with you that low stratus can often cause a "blanket effect" and keep temps up especially during nocturnal hours. However, they also...
I'm highly skeptical that climate models will ever be able to accurately depict cloud cover decades in the future, based on my experience with NWP...
I'm not necessarily advocating or even suggesting that diesel in Prius makes sense. I'm just disputing that modern diesels are the "environmental...
Actually, GrumpyCabbie, I'm perplexed by your adamant attack on diesel emissions. I thought I've seen posts from you highlighting how clean the...
Actually, I'm not an engineer. I served as an air quality forecaster in the U.S. NOAA from 2004-2012 (Retired in 2012). I have been involved in...
Even if that is true (and I'd like to see actual monitoring data to be convinced diesel is the problem), it's because of legacy diesels. As I'm...
Then the EU needs to start focusing on particle emissions from direct-injection GASOLINE (GDI) engines... "…Compared to diesels, a bigger...
With all due respect to Jennifer Francis of Rutgers and others who are convinced that weakening upper flow dynamics will necessarily result in...
Actually, most of the particles emitted by petrol engines are in the extremely small size category - nanoparticles - typically defined as <50...
