Most Popular. From 'Back in Black' to a trillion dollar debt, is the government's conversion to Keynesianism complete? Fahrenheit temperature scale. To work out a temperature in degrees Fahrenheit degrees F , multiply the temperature in degrees C by 1. So 10 degrees C is the same as 50 degrees F. The name Tsunami is used to describe a series of waves travelling across the ocean. These waves can measure up to hundreds of kilometres between wave crests in the deep ocean.
They are very fast moving, and unlike normal waves, affect the movement of the water all the way to the sea floor. They tend to get higher as they get closer to land and, if high enough when they reach the land, can travel far inland and cause very serious damage. Earthquakes are one of the things that cause tsunami. They can also be caused by underwater landslides, volcanoes, land slipping into the ocean, meteors, or even the weather when the atmospheric pressure changes very rapidly.
The most common cause of tsunami is an under sea earthquake with a sudden change in a section of the earth's crust under or near the ocean.
This rise or fall in sea level makes a tsunami wave. Electromagnetic radiation with wavelengths shorter than visible light, but longer than x-rays. Exposure to too much UV radiation can cause skin cancer. Upward moving current of air of small dimensions. A rapidly moving vertical wind as found in thunderstorms. Water available, or capable of being made available, for use in sufficient quantity and quality at a location and over a period of time appropriate for an identifiable demand.
Determination of the sources, extent, dependability and quality of water resources for their utilisation and control. The atmospheric pressure which is exerted by water vapour water in its gaseous state. It is one way of measuring the humidity of the air. At a given temperature, an increase of water vapour in the air corresponds to an increase in the humidity of the air. Water vapour is supplied to the atmosphere by evaporation of water from oceans, lakes, wet land surfaces or from vegetation transpiration.
Water vapour absorbs the Sun's radiation. As a result, the sunlight received at the Earth's surface will be more intense in a drier atmosphere. Wet-bulb temperature is measured using a standard mercury-in-glass thermometer, with the thermometer bulb wrapped in muslin, which is kept wet. The evaporation of water from the thermometer has a cooling effect, so the temperature indicated by the wet bulb thermometer is less than the temperature indicated by a dry-bulb normal, unmodified thermometer.
The rate of evaporation from the wet-bulb thermometer depends on the humidity of the air - evaporation is slower when the air is already full of water vapour For this reason, the difference in the temperatures indicated by the two thermometers gives a measure of atmospheric humidity.
Usually only one wind speed is given in a weather forecast, unless it is expected to be very gusty. For instance, fresh, gusty southwest winds means that wind speed will generally be between 17 and 21 knots or about 30 to 38 kph and the mean wind direction will be from the southwest, but that there will also be much stronger gusts.

Advection The sideways movement of air in the lower atmosphere due to the differences in air pressure commonly called wind. Anomaly The departure of an element from its long-period average value for the location concerned. Anticyclones Atmospheric circulations that rotate anti-clockwise in the southern hemisphere. Barometer A tool to measure air pressure which lets us predict change in weather.
Beaufort wind scale A scale that uses observations of the effects of wind to estimate its speed. Blizzard Violent and very cold wind which is loaded with snow, some of which has been raised from snow covered ground. Carbon dioxide A gas CO 2 present in the atmosphere which plays an important role in the greenhouse effect. Celsius temperature scale Thermodynamic scale of temperature. Chlorofluorocarbons Chemicals that release chlorine atoms that destroy ozone high in the atmosphere. Cirrus cloud High cloud, delicate, hair-like and feathery looking.
Climate The atmospheric conditions for a long period of time, and generally refers to the normal or mean course of the weather. Cloud A group of water drops or ice crystals that can be seen in the sky, caused by water vapour rising and cooling.
Cloud cover Forecasting terms: Clear: Free from cloud, fog, mist or dust haze. Sunny: Little chance of the sun being hidden by cloud. Cloudy: More cloud than clear sky. For example, during the day the sun would be hidden by cloud for a lot of time. Overcast: Sky completely covered with cloud. Combined Sea and Swell Also known as total wave height, or significant wave height.
Convection The movement of warm air, rising off the land, which helps to make cloud, local breezes, wind and thunderstorms.
Cumulonimbus cloud Heavy, puffy, heaped, dark very tall clouds often bringing rain. Cumulus Clouds with a woolly, heaped appearance that often produce rain. Cyclogenesis The rapid development of a low or intensification of a pre-existing one. Cirrus cloud High cloud, delicate, hair-like and feathery looking, that may be seen on 'fine' days.
Desert There are many different definitions which describe a desert. Dew Droplets of water deposited when air cools and the water vapor in it condenses. Dew-point temperature This is a measure of the moisture content of the air and is the temperature to which air must be cooled in order for dew to form. Downburst Violent and damaging downwards flow of air hitting the surface of the Earth violently, usually in a severe thunderstorm. Drizzle Steady rain in very small water droplets less than 0.
Drought Drought is a long, unusually dry period when there is not enough water for normal needs. Dry-bulb temperature This is the shade temperature degrees Celsius registered by a mercury-in-glass thermometer exposed in a white louvered box or meteorological screen which is raised on legs one metre above the ground. Dry As used by forecasters Free from rain. Dust storm A wind storm which carries large amounts of dust or sand high into the air and may drop them far away e.
East Coast Lows East Coast Lows are intense low-pressure systems which happen on average several times each year off the eastern coast of Australia, in particular southern Queensland, NSW and eastern Victoria. Equatorial trough Zone of relatively low pressure which lies between the subtropical anticyclones of the two hemispheres.
Fahrenheit temperature scale Thermodynamic scale of temperature. Fine Dry weather with no rain of any kind, hail or snow. Flash Flood Flood of short duration with a relatively high peak discharge. Flood A flood occurs when water inundates covers land which is normally dry. Flood Forecasting Scientific opinion, based on past records and on weather and water conditions, about the likely height, amount of water, and time a flood will probably happen, and go on for, at a particular place on a river, stream or over land.
Flood Warning Official advance notice that a flood may happen soon at a certain place or near a certain river. Fog A dense mass of small water droplets or particles in the lower atmosphere. Front The boundary between air masses having different characteristics.
Front Cold In some regions along the polar front, cold dense air advances equatorwards, causing warm air to be forced aloft over its sloping surface. Front Warm In other regions along the front, warm air of lower density moves polewards, sliding over its sloping surface.
Frost Deposit of soft white ice crystals or frozen dew drops on objects near the ground; formed when surface temperature falls below freezing point. Gale Warning A Gale Warning is a statement which warns of sea winds averaging from 34 knots and up to 47knots equal to about 60 - 85 kph in coastal waters and out at sea. Greenhouse effect A natural warming process of the earth. Global radiation Global short wave radiation includes both that radiation energy reaching the ground directly from the sun, and that received indirectly from the sky, scattered downwards by clouds, dust particles etc.
Gust A gust is a sudden burst of stronger wind that usually only lasts a few seconds. Hail Small roundish pieces of ice 'hailstones' generally between 5 and 50 millimetres across, which fall from clouds as separate bits or in clumps.
Heat wave A period of abnormally hot weather lasting several days. High pressure Atmospheric circulations that rotate anti-clockwise in the Southern Hemisphere. Humid Moisture in warm air. Humidity Moisture in warm air. Hurricane Force Wind Warning A Hurricane Force Wind Warning is a statement which warns of winds averaging 64 knots or more in coastal waters and high seas areas.
Hydrology An earth science concerned with the occurrence, distribution and circulation of waters on and under the earth's surface, both in time and space, their biological, chemical and physical properties, their reaction with the environment, including their relation to living beings.
Hydrometeorology The study of the atmospheric processes that affect the water resources of the earth, including the study of the atmospheric and land phases of the hydrological cycle with emphasis on the interrelationships involved. The gale had not abated — in fact frayed nerves made it seem stronger. In the grey even the radio newsreader confessed no one in Townsville knew the state of the city.
At first I was too frightened to venture outside, but by 6am I decided to head out on my bicycle to find out what had happened to the city. The roads were covered in trees — huge behemoths that only days earlier had formed a shady avenue that gave respite from the tropical sun when I rode my daughters to school.
With them came down power lines. In many streets I passed, the way was blocked by poles and wire tangled up in fallen trees like cobwebs. The road and footpaths were covered in a carpet of shredded leaves.
