You may ask, "what about the mathematics used in meteorology?" Many people wonder how math relates to meteorology.
Math and weather have always been two of my favorite subjects. Math helps me understand the world around me, and weather is just fascinating. Temperature, pressure, and wind interact to create the weather we experience.
Does meteorology require math skills? It can't hurt - that's for sure.
The science of meteorology relies heavily on math and physics. You can use weather radar, interpret charts (like the hodograph on the right), and predict the weather numerically. The sketch shows five simultaneous winds speeds at a single geographical point, each at a different elevation above ground.
Meteorologists study the atmosphere. Among other things, they look at and predict the weather and air pollution.
We also use instruments to measure wind speed and direction, temperature, pressure and humidity. We can then understand how these different quantities, sometimes called fields, interact with each other with scientific theory. And how the variables change in time and space.
Variables are unspecified quantities that can take on different values under different conditions.
In math, we use the letters x and y for most problems. Mathematicians use them to determine or assign specific values to variables based on the circumstances of the problem.
Variables for the mathematics used in meteorology include:
Meteorology is a three-dimensional science, four if you include time, so the mathematics can require partial derivatives a lot. What's that? You can use partial derivatives to see how something like wind speed changes when you move in one direction only, like straight north. Pilots might find this useful. We can also figure out the gradient of a field with them. For instance, figuring out what direction to move in to see the biggest temperature increase. Even how much it increases after moving a certain distance.
The mathematics used in meteorology could, and does, fill textbooks quite extensively. Atmospheric Science - An Introductory Survey by Wallace and Hobbs and An Introduction to Dynamic Meteorology by James R. Holton are good starters Go Nuts!
I just about did.
A centripetal force equation, for example, relies on balancing physical properties. Then each force is defined by products and derivatives of other parameters. Then they're strung along as terms added together, each a component of the net force. Sometimes, but not always.
What other fields of study use the same mathematical principles? Physics, climatology, hydrology, and atmospheric chemistry.
Weather forecasting dates back to ancient times, when people used observations of the sky and natural phenomena to predict the weather. We got better though.
Meteorologists have developed sophisticated computer models and technologies to create increasingly accurate weather forecasts since they started using scientific methods in the 1800s.
What's math without a few computers? Lewis Fry Richardson wrote Weather Prediction by Numerical Process in 1922. He proposed that we could simplify meteorology math by looking at small parametric changes with respect to small physical motions instead of these abstract equations. Thus, simple algebra could help us explain the complex principles.
It was labor-intensive, though. With this primitive method, 64000 people would be needed to make the calculations to predict the world's weather. His results were also pretty poor.
Little did he know about computers to be invented just a few decades later. They would really help with the mathematics used in meteorology. In the mid-20th century, computers revolutionized weather forecasting by allowing scientists to input huge amounts of data and do complex calculations. In order to simulate the behavior of the atmosphere and make detailed forecasts, numerical weather prediction (NWP) models were developed. They made Richardson's calculations go more efficiently.
They've improved since then, believe it or not. We rely on models a lot now. Meteorologists had more data to work with in the 1970s and 1980s with weather satellites and other advanced technologies. The most advanced weather forecasting models today use data from satellites, weather balloons, and ground-based sensors to make highly detailed and accurate forecasts up to a few days in advance.
Because they've incorporated things like chaos theory and can give ensemble forecasts, which allow for changing probabilities and small changes in statistics. We will continue to develop more sophisticated technologies and mathematics used in meteorology to predict the ever-changing patterns of the atmosphere.
As such, the history of weather forecasting is an ongoing story of innovation and improvement. It just keeps getting better. Thanks to the mathematics used in meteorology.
At least that's what some people think. Do you think math helps us to understand our world? Succeed at work? Use a computer?
You bet. That reminds me, it can help make you a better gambler if you're so inclined.
