Weather and Tools
Graphing Weather Conditions
Measuring and tracking weather conditions is an important tool scientists use to understand how weather can be predicted.
This is a graph showing the monthly average high temperatures in Anchorage, Alaska compared to Miami, Florida.
As you can see from the chart, Anchorage is constantly colder, especially in the winter. On average, in Miami it is a lot warmer, especially in the summer.
Miami is a lot warmer than in Anchorage because Miami is closer to the equator. The equator is a imaginary line that separates the Earth into two hemispheres, Northern and Southern.
The equator is the hottest point on earth because it is the closest point to the sun. The earth tilts on its axis and the sun beams down on it.
Anchorage is cooler than Miami because it is further away from the equator than Miami.

Tools for Measuring Weather Conditions
There are a variety of instruments used to measure weather conditions. Some of these are:
- Wind Speed and Direction - Wind direction is measured with a wind vane and wind speed is measured with an anemometer. This helps us to determine the daily forecasts. Also, it can help meteorologists determine if it is a high or low pressure. At the equator it is usually a low pressure because it is the warmest point on earth. It is also stormy because low pressure is where it is stormy, warm, and or humid.
- Precipitation- Precipitation is rainfall, snowfall, hail, and, or sleet. The rain gauge will also help meteorologists predict the forecasts. When it is rainy it is a low pressure because rain is stormy weather or lousy weather.
- Temperature- Temperature is measured with a thermometer. The thermometer will tell us how hot or cold it is.
- Air Pressure - The air pressure is measured with a barometer. There are two types of air pressures. One being low pressure and one being high pressure. Low pressure is when it is stormy, warm, and, or humid. On the other hand high pressure is when it is sunny and cooler. To remember high and low pressure, high pressure is happy, while low pressure is lousy.

Barometer - measures air pressure
A barometer is a weather tool used for measuring air pressure. Because a change in air pressure is a sign of changing weather, this instrument is one of the main tools of the weather forecaster. A "falling" barometer means that a low-pressure mass of air is approaching. Such low-pressure generally brings storms. A "rising" barometer usually means an approaching high-pressure air mass and sunnier weather.
