Violent storms are also known as typhoons or hurricanes. They can result in millions of dollars worth of property damage and cause the deaths of thousands of people. The best you can do when disaster strikes is to prepare yourself and arm yourself with survival tips during super typhoons.

Preparing for the super typhoon

If there's any sign of a bad weather, tune in to a weather station for news advisories. Before the typhoon even strikes, be sure to have a good supply of water, food, and light source such as battery-operated flashlights, candles, and emergency lights. You must have a good supply of dry food and canned goods as well, and remember to keep a can opener handy. Gather items of clothing that can protect your from rain, cold, or any extreme weather condition. To protect your home, close the windows and secure the doors. Best of all, turn off propane tanks and utilities that use gas to prevent explosion once the typhoon starts to strike. Also remember to unplug home appliances to avoid fire accidents.

What to do during the super typhoon

Keep away from glass windows to avoid injuring yourself with flying objects. Also keep life jackets handy. To avoid flooding inside your home, check for water leaks and seal them off. Stay tuned to weather reports so you'll know what to do and if it's time to leave the house for evacuation. Don't wait until the water level (in case of floods) gets too high that it would be nearly impossible for you to get out of the house. Try to be calm because panic can likely cause mistakes with the way you handle emergency situations.

During disasters, authorities issue warnings and advisories. You should not ignore these, as these can save your and your family's life. Prepare for the worst thing that can happen. This would be the key to your survival.

Although it is a very simple device, thermometers are essential tools in weather forecasting.

How a thermometer (for weather) works

A thermometer shows us the air temperature. Most thermometers work by using a substance that expands when heated and contracts when cooled, such as alcohol, mercury, or certain kinds of metal. Alcohol or mercury is placed in a thin tube, with marking alongside the tube. When heated, the alcohol or mercury goes up the tube as it expands. The markings beside the tube show us the temperature, usually in Celsius and Fahrenheit. Other thermometers use a metal spring attached to a pointer. When this metal expands or cools according to the amount of heat present in air, the pointer moves to the corresponding temperature.

Types of thermometers used in weather monitoring

As mentioned above, thermometers can be of the alcohol, mercury (collectively known as expansion thermometers), or spring type. Digital thermometers can also be used for weather monitoring. These thermometers use a device called a thermistor to measure temperature, and display the temperature on a screen. Infrared or laser thermometers, which measure the temperature by detecting radiation emitted by objects, although not commonly used in weather monitoring, can be employed to detect clouds.

Regardless of the type of thermometer used, measuring air temperature is an indispensable part of weather monitoring.

The instrument used to measure atmospheric pressure is the barometer. It measures the atmospheric pressure through water, air, or mercury in the gadget itself. It is used in weather prediction by determining fair weather from high air pressure or low pressure to determine storms. Short term forecasts are made when observing the wind.

How a barometer works

Pressure is indicated by the barometer's dial, expressed in inches or the inches of mercury. Dial barometers use an air pressure sensor that applies a limited range of sensitivity. Typically, the range covers between 3000 and 4000 feet. The air placing pressure on the mercury makes it go up the barometer’s glass. On the earth’s surface, air pressure goes up to about 30 inches.

Types of barometers used in weather monitoring

Aneroid barometers are made of beryllium and copper alloy. Minimal air pressure changes easily to make the cell expand or contract. The movements are amplified in the aneroid barometer’s face. The needle indicates the measurement that characterizes the change. Falling barometers mean precipitation is occurring while rising barometers indicate fair weather.

Barometers are easy ways to understand the weather. Having one in your home will allow you to make plans for the future or do the gardening accordingly. Many weather stations use barometers to predict major events such as storms or strong winds. There are many barometer devices available in major weather stores. The basic mercury barometer is typically displayed in science laboratories. You could even find one around public buildings or universities.
