Python Programs for Meteorology

Interactive computational tools for atmospheric analysis and visualization

🌐 Browser-Based Python Execution

Run Python code directly in your browser using Pyodide, a Python runtime compiled to WebAssembly. No installation required - the code executes entirely in your browser!

✓ No Setup

Python environment loads automatically in browser

✓ Editable Code

Modify the code and experiment with parameters

✓ Instant Plots

Matplotlib figures render directly in the page

⚠️ First run downloads the Python environment (~15MB). Subsequent runs are faster.

1Weather Data Visualization

Generates synthetic 7-day weather data and creates a multi-panel visualization showing temperature, humidity, and wind speed with daily cycles and realistic variation patterns.

2Atmospheric Stability Analysis

Analyzes an atmospheric sounding to calculate CAPE (Convective Available Potential Energy), CIN (Convective Inhibition), and the K-Index for thunderstorm forecasting.

Key Equations

\[\text{CAPE} = \int_{z_{\text{LFC}}}^{z_{\text{EL}}} g \frac{T_{\text{parcel}} - T_{\text{env}}}{T_{\text{env}}} \, dz\]

3Skew-T Log-P Diagram

The Skew-T log-p diagram is the most widely used thermodynamic diagram in meteorology. It displays temperature and dewpoint profiles with reference lines for analyzing atmospheric stability.

Diagram Features

• Blue lines: Isotherms (constant T)
• Red lines: Dry adiabats (constant θ)
• Green lines: Moist adiabats
• Cyan dashed: Mixing ratio lines
