Scientists gather information from all of these sources. They use computers to organize the information.
The computers help the scientists to develop models to predict what the weather will be like.
Weather is complex and changing. As such, it’s important to remember that weather forecasts are just _______.
They can never tell you exactly what is going to happen. The closer they get to the weather event, the more _______ they are.
There are many different factors that can affect weather including the sun, land formations, and ________________.
The energy that Earth receives from the sun is a major driving force in our ____________.
The heat from the sun warms the ___________ ____________. It doesn’t heat Earth the same all over. This causes differences in temperature which result in warm and ___________ air masses.
The day/night cycle is another factor in weather, causing warmer temperatures during the day and _______________ temperatures at night.
Land and water heat unevenly. Land heats faster than water, but it also cools off ______________. The ____________ heating of Earth leads to uneven pressure distribution which creates ___________ and ____________ pressure distribution. Air moves from high to low pressure systems which creates ______________.
Much of Earth experiences ____________________ differences in weather such as changes in temperature and precipitation. That’s because Earth does not stay still. It revolves around the __________.
Landforms like hills and mountains can affect the weather, too. For example, think about what happens as wind hits a barrier like a mountain. It is pushed upwards and spreads out. As a result, the wind loses some of its ________. When the air flow goes upward, it becomes cooler, causing the water in the air to ________. Precipitation begins to fall and can create heavy rainfall on the base and slopes on that side of the mountain. Once the air reaches the other side of the mountain, the strength of the wind is ___________and the air has less moisture.
Weather forecasts are just predictions and can never accurately tell you exactly what is going to happen. The closer they get to the weather event, the more accurate they become.
There are many different factors that can affect weather, including the sun, land formations, and the rotation of Earth. The energy that Earth receives from the sun is a major driving force in our weather. The heat from the sun warms the Earth's surface, creating differences in temperature that result in warm and cold air masses. The day/night cycle also plays a role in weather, with warmer temperatures during the day and cooler temperatures at night.
Land and water heat unevenly, with land heating faster than water. This uneven heating leads to differences in pressure, creating wind and atmospheric motion. Air moves from areas of high pressure to areas of low pressure, creating weather systems.
The rotation of Earth leads to differences in weather across different regions. Earth's revolution around the sun also contributes to seasonal weather changes.
Landforms like hills and mountains can affect weather as well. When wind hits a mountain, it is forced to rise, cool down, and release moisture, leading to precipitation on one side of the mountain. On the other side, the wind is weakened and has less moisture.
Overall, weather is a complex and dynamic system influenced by numerous factors that scientists gather and analyze through computer models in order to make predictions.
