Accepted at Atmospheric Chemistry and Physics after nearly two and half years

On 25 January 2013, 904 days from the date it was submitted (5 August 2010), a manuscript was finally published at Atmospheric Chemistry and Physics. Not only was this manuscript noteworthy for how long it remained in limbo before a final thumbs up or thumbs down from the Editor, but it was noteworthy for other … read more

“Cold” equivalent potential temperature?

As scientists, we need to be precise in our writing. Evgeni Fedorovich at the University of Oklahoma has tried to keep me honest about writing about “cold temperatures”. Know that the air can be “cold” or “warm”, but temperatures are “high” or “low.” I want to take this argument one step further. It makes no … read more

Case studies: Do I need multiple cases to make my point?

My colleague Russ Schumacher and I have been discussing a paper that we want to write about banded precipitation along the Front Range of the Rockies. Russ has seen multiple events each winter, and the processes that produce these bands are not well understood, even though we have already written a couple of papers on … read more

Best Practices for Numerical Weather Prediction Studies

The late Tom Warner of the National Center for Atmospheric Research just published an article entitled “Quality Assurance in Atmospheric Modeling”. You may not get it from the title, but this is a powerful paper that lays out 14 steps for improving modeling practices. All students and users of models need to read this paper … read more

Plain English Campaign gets it wrong

In almost all cases, I support the Plain English Campaign, who aim to improve the readability of government documents, corporate letters, web sites, and other forms of communication. In their 2011 Golden Bull Awards, however, the Plain English Campaign got it dead wrong. The UK Met Office won an award for ‘empowering people to make … read more

Petterssen, Palmén and Newton, Carlson, and Lackmann

I am honored to have seen page proofs of Gary Lackmann’s new book Midlatitude Synoptic Meteorology: Dynamics, Analysis, and Forecasting to be published later this year by the American Meteorological Society. For this book, Gary goes back to the original meaning of the word synoptic (“forming a summary or synopsis”). Twelve chapters summarize and synthesize … read more

Problems with the term “overrunning”

Several authors have criticized the use of the term overrunning to represent warm-frontal lifting here and here. I don’t need to add anything to those Web pages, but I do want to point out that the definition provided in the American Meteorological Society’s Glossary of Meteorology is wrong and ambiguous. overrunning—A condition existing when an … read more

Is it in your nature to use “nature” in your scientific writing?

Some authors have a habit of using the word “nature” commonly in their writing. I suspect that they don’t even think about it. It just seems, well, natural. In fact, the word is empty of meaning in many contexts. “cumuliform nature”: “the cauliflower-like visual appearance of convective clouds” “nature of the convection”: What do you … read more

Potential Temperature: Warm and Cold?

Does it make sense to talk about air with high values of potential temperature or equivalent potential temperature as warm or cold? I don’t think so, so I recommend talking about “air with higher or lower potential temperature” instead. Although it is wordier than warm or cold, the meaning is precise.

Thermodynamic diagrams for free

Upon packing up my house in Oklahoma, I discovered a small stash of Skew T–logp thermodynamic diagrams that I had saved when Charlie Crisp cleaned out his office at NSSL. (I also have a huge stash of blank U.S. surface maps, in case anyone is interested in them.) Geraint Vaughan at Manchester had been lamenting … read more
