Forecasting the weather requires looking ahead. The Euro 700 mb Vertical Velocity 24 chart is a predictive tool that shows us what the atmosphere will be doing 24 hours from the model initialization time. By analyzing this map, meteorologists can anticipate where storms will develop or where skies will clear tomorrow.
What Does the Euro 700 mb Vertical Velocity 24 Show?
This specific chart displays the predicted vertical velocity at the 700 mb (or 700 hPa) level for the next day. Unlike the “00” analysis which shows the current state, the 700 mb Vertical Velocity gives you a glimpse into the future.
It visualizes the vertical motion of air, which is essential for predicting precipitation. Since this is a 24-hour forecast, it is perfect for short-term planning.
Interpreting the Forecast: Colors and Vorticity
To understand the 700 mb Vertical Velocity map, you need to interpret the color scale correctly regarding atmospheric physics and vorticity.
1. Red Areas (Positive Values)
The red and orange zones represent positive vertical velocity.
- What it means: The air is sinking (subsidence).
- Weather Outlook: Sinking air warms and suppresses clouds. Therefore, these areas usually indicate high pressure and stable weather for the next 24 hours.
- Physics: This is often associated with Negative Vorticity Advection, which pushes air downward.
2. Blue Areas (Negative Values)
The blue zones represent negative vertical velocity.
- What it means: The air is rising (uplift).
- Weather Outlook: Rising air cools and condenses. Consequently, these are the target areas for rain, snow, or thunderstorms.
- Vorticity Connection: Strong blue signals on the map are often driven by Positive Vorticity Advection. When positive vorticity moves over an area, it creates lift, resulting in the blue signatures you see here.
Conclusion: Euro 700 mb Vertical Velocity 24
In summary, the 700 mb Vertical Velocity 24 hour chart is your roadmap for tomorrow’s weather. By monitoring the blue uplift zones (linked to positive vorticity) and the red subsidence zones, you can accurately predict weather changes 24 hours in advance.
