It tells you whether or not the pressure is rising or falling. A rising pressure means sunny and dry conditions, while a falling pressure means stormy and wet conditions.

If the surrounding air is relatively dry, more moisture will evaporate from the wet bulb, and the drop in temperature will be higher. If the air is more humid, evaporation will be less, and the fall in temperature will be lower. Which weather tool determines the humidity of the atmosphere?

A weather tool that determines the wind speed in miles per hour (mph), kilometers per hour (kph), meters per second (m/s), or knots.

It is an instrument used for showing the direction of the wind. It is typically used as an architectural ornament to the highest point of a building. The word vane comes from the Old English word fana, meaning "flag".

It is an instrument used by meteorologists and hydrologists to gather and measure the amount of liquid precipitation over a predefined area, over a period of time.

It is also known as sounding balloon, that carries instruments aloft to send back information on atmospheric pressure, temperature, humidity and wind speed by means of a small, expendable measuring device called a radiosonde

It's shape and position tell the direction and speed of the wind in the sea.

These weather instruments have sensors that scan the Earth, taking measurements of reflected light and infrared temperatures. These measurements are then digitized and sent back to Earth where they can be turned into images.

PAGASA stands for:

It is a report that tells what an area’s weather will be during a certain period of time.

It provides information to the public about the weather conditions that may affect their location and allow them to make the necessary preparations.

In the Color Coded Rainfall Advisories of PAGASA, how much rainfall do we expect on an orange warning alert?

Using the official weather Icons of PAGASA, what does the picture on the left mean?

Climate is the average weather for a particular region and time period, usually taken over 30-years. Weather means:
