METEOROLOGY – HUMIDITY & WATER VAPOUR CALCULATOR
Lake Evaporation Monthly
A precise tool.
What is the Lake Evaporation Monthly & How does it work?
Evaporation is the process by which water changes from a liquid to a gas. In meteorology, understanding evaporation rates is crucial for predicting weather patterns and managing water resources.
The pan factor method is commonly used to estimate lake evaporation. It involves measuring the evaporation rate from a large open container (pan) placed on the surface of the lake. The pan factor adjusts for differences between the actual lake surface and the pan surface.
E = P times F
E = Evaporation rate (mm/month), P = Pan evaporation rate (mm/month), F = Pan factor

Frequently Asked Questions
What is the pan factor in lake evaporation?
The pan factor adjusts for differences between the actual lake surface and the pan surface used to measure evaporation.
How do I use this calculator for lake evaporation?
Input the measured evaporation rate from a pan placed on the lake and apply the appropriate pan factor to estimate lake evaporation.
Why is understanding evaporation rates important in meteorology?
Understanding evaporation rates helps predict weather patterns and manage water resources effectively.
What is the formula used for calculating lake evaporation?
The formula used is E = P × FE, where E is the evaporation rate, P is the pan evaporation rate, and FE is the pan factor.
Can this calculator be used for any body of water?
While primarily designed for lakes, this calculator can be adapted for other bodies of water with similar surface characteristics.
How often should I measure evaporation rates to use this calculator effectively?
Measure evaporation rates monthly to get a consistent and reliable estimate using the pan factor method.
