Key Idea.
Section 1
Weather Reveals a Yearly Pattern
The weather on any single day can be a surprise. A summer day might be cool and cloudy, while a winter day could be sunny and mild. These daily changes can make the weather seem unpredictable.
However, looking at the weather over many months reveals a larger, predictable pattern. This pattern shows the usual kind of weather for different parts of the year. This same general pattern repeats each year, creating a cycle.
Section 2
Scientists Use Patterns to Predict Weather
By studying weather data from the past, scientists find a repeating pattern in how the weather changes throughout the year. This pattern shows the typical weather for each season in a location.
Once a pattern is known, it can be used to predict what the weather will likely be in the future. A prediction is a smart guess based on information that has been collected over time.
Section 3
Weather Repeats in a Yearly Cycle
The weather in a place changes throughout the year. Some months are warmer, and others are cooler. Some parts of the year might be very rainy, while others are dry.
This pattern of weather changes repeats every year in a predictable way. This repeating annual pattern is known as a seasonal cycle. Each part of the cycle is a "season" with its own typical weather.
