Understanding the difference between Standard Deviation (SD) and Standard Error (SE) is crucial for accurate data interpretation. SD measures the variability within your data, indicating how spread out the individual data points are from the mean.
In contrast, SE measures the uncertainty around the sample mean as an estimate of the population mean. It reflects the precision of the mean, with SE decreasing as the sample size increases, making your estimate more reliable.
The relationship between SD and SE is given by the formula: SE = SD / √(sample size). While SD remains relatively constant with larger samples, SE diminishes, highlighting the reduced uncertainty in the mean estimate.
A common mistake in research is using the “±” notation without specifying whether it refers to SD or SE, leading to potential misinterpretation of the data. Clear distinction is essential for transparency and accuracy in reporting.
Key Takeaways:
• Use SD to describe data variability.
• Use SE to indicate the precision of the mean.
• Always specify which measure you are reporting.
The horrible living conditions #Auschwitz & the appalling sanitary conditions contributed to the exhaustion & death of many prisoners in the camp.

So if you thought there was nothing more to say about the baroclinic Eady problem, here is a paper detailing some more random things about it. Touches on #waves, #dynamicalsystems, #quantum#physics (PT symmetric system, even though system is classical).

The westward moving features are Tropical Instability Waves from shear instability between eastward & westward flowing equatorial currents.
Building on decades of progress in El Niño–Southern Oscillation (ENSO) modeling, researchers have developed a new model that provides accurate ENSO forecasts as much as 16–18 months in advance. https://t.co/F1SiXIe6u3
If you’re interested in climate/weather, it’s worth reading Project 2025’s recommendations for NOAA. Summary (p664): “(NOAA) should be dismantled & many of its functions eliminated, sent to other agencies, privatized, or placed under the control of states” 🧵
I'm happy to announce a new paper, with @baylorfk, Joel Feske, and @jeffreyearly.
Integral theorems for the gradient of a vector field, with
a fluid dynamical application
It's hopefully useful to oceanographers as well as those working with tensors.

Dear @YouTube. Today marks the 84th anniversary of the deportation of the first Poles to Auschwitz. 14 June 1940 was the beginning of the operation of this German Nazi camp. Let’s all honor their memory by sharing this short video about their history: https://t.co/LG93JOr7at
@thirstygecko @OceansClimateCU Twitter / X is such a cesspool. The only time I see your @OceansClimateCU science Twitter posts now is when Russian bots and far right do a pile on of disinformation.
Someone from @piersmorgan's staff asked if I would like to come onto Pier's show, Piers Morgan Uncensored, to talk about the state of his attire. Since he invited feedback, I thought I'd do a thread comparing his style to menswear icon Kermit the Frog. 🧵
