🚜 The Farmers' Almanac bids a tearful #goodbye by putting on a grand #circus of ads, subscriptions, and calendars you'd never use. Clearly, they're hoping you'll get lost in the clutter and accidentally buy something. 🎪 Who knew predicting the weather required this much spam? 🌧️📅

Basics of Numerical Weather Prediction (NWP):

1. THE HORIZONTAL MOMENTUM EQUATION:
\[
\frac{d\mathbf{V}}{dt} + f\hat{k} \times \mathbf{V} = -\nabla \phi + \frac{\sigma}{p_s} \frac{\partial \phi}{\partial \sigma} \nabla p_s + \mathbf{F}
\]

2. THE CONTINUITY EQUATION:
\[
\frac{\partial p_s}{\partial t} + \nabla \cdot (p_s \mathbf{V}) + \frac{\partial}{\partial \sigma}(p_s \dot{\sigma}) = 0
\]

3. THE THERMODYNAMIC ENERGY EQUATION:
\[
\frac{1}{R} \frac{d}{dt} \left[ \sigma \frac{\partial \phi}{\partial \sigma} \right] + \frac{RT}{C_p p} \left[ p_s \dot{\sigma} + \sigma\dot{p_s} \right] = -Q
\]

4. HYDROSTATIC EQUATION:
\[
\frac{\partial \phi}{\partial \sigma} = -\frac{RT_v}{\sigma}
\]

5. SURFACE PRESSURE TENDENCY EQUATION:
\[\displaystyle
\frac{\partial p_s}{\partial t} = -\int_{0}^{1} \nabla\cdot (p_s \mathbf{V}) \, d\sigma
\]

6. MOISTURE EQUATION:
\[\displaystyle
\frac{\partial}{\partial t} (p_s q) + \nabla\cdot (p_s q \mathbf{V}) + \frac{\partial}{\partial \sigma} (p_s q \dot{\sigma}) = p_s S
\]

The six primary unknowns are: \(\mathbf{V}\) (horizontal wind velocity), \(p_s\) (surface pressure), \(T\) (temperature), \(q\) (specific humidity or moisture), \(\phi\) (geopotential), and \(\dot{\sigma}\) (sigma velocity or vertical velocity in \(\sigma\)-coordinates).

Convective storm detection (Storm 🌪️)

Convective storm detection is the meteorological observation, and short-term prediction, of deep moist convection. DMC describes atmospheric conditions producing single or clusters of large vertical extension clouds ranging from cumulus congestus to cumulonimbus, the latter producing thunderstorms associa...

"Let’s talk about weather balloons—a.k.a. radiosondes—and why recent cuts to NWS staffing and balloon launch schedules are putting the public at risk (eg., Deaths in Texas). No satellite or model can replace what these humble balloons do. Here's why. " - #AltNOAA

Despite all the hype, #AI chips are making startling advances in science. Numerical #weatherprediction takes hours to run on a supercomputer with 10's of thousands of cores. After one week of training, a machine learning model can produce better results on a single #tensor processing chip in just 8 minutes. The forecast is good out to 15 days. https://www.theguardian.com/science/2024/dec/04/google-deepmind-predicts-weather-more-accurately-than-leading-system
