Separating almond evapotranspiration into soil water evaporation and crop transpiration

Separating Almond Evapotranspiration

The estimation of crop water use is a key input into much of the software which supports irrigation management. The most common method used to derive this estimate is to calculate it from weather data and coefficients specific to crop type and growing…

Weather drivers in Victoria

Communicating Climate Change - Module 1

The driving force behind our weather is the general circulation of the atmosphere, caused by unequal heating of the Earth’s surface. Energy from the sun causes evaporation from the tropical oceans and uneven heating of land and sea surfaces near the equator. An extensive area of high pressure, known as the sub-tropical ridge, is a major feature of the general circulation of our atmosphere. It is a major influence on the climate of southern Australia. Its position (more)...

Climate change: the scientific basis for concern

Communicating Climate Change - Module 1

The climate of the Earth is changing; it always has and always will. At very long time scales, natural drivers of climate change include subtle shifts and wobbles in the Earth’s orbit. These shifts account for the ice ages and warm interglacial periods over the last million years. At decadal time scales, natural climate drivers include variations in ocean currents and solar output. At the annual scale, drivers such as volcanic eruptions (which cool the earth by adding reflective (more)...

Weather drivers in Western Australia

Communicating Climate Change - Module 1

The driving force behind our weather is the general circulation of the atmosphere, caused by unequal heating of the Earth’s surface. Energy from the sun causes uneven heating of land and sea surfaces near the equator and evaporation from tropical oceans. An extensive area of high pressure, known as the sub-tropical ridge, is a major feature of the general circulation of our atmosphere. This belt of high pressure encircles the globe at the middle latitudes. The position (more)...

Weather drivers in South Australia

Communicating Climate Change - Module 1

The driving force behind our weather is the general circulation of the atmosphere, caused by unequal heating of the Earth’s surface. Energy from the sun causes uneven heating of land and sea surfaces near the equator and evaporation from tropical oceans. An extensive area of high pressure, known as the sub-tropical ridge, is a major feature of the general circulation of our atmosphere. It is a major influence on the climate of southern Australia. The position of the ridge varies with (more)...

Weather drivers in Queensland

Communicating Climate Change

The climate of Australia varies across many different regions and timescales. Here we introduce the major elements that affect the weather and climate of Queensland. The driving force behind our weather is the general circulation of the atmosphere, caused by unequal heating of the Earth’s surface. Energy from the sun causes evaporation from tropical oceans and uneven heating of land and sea surfaces. An extensive area of high pressure, known as the sub-tropical ridge, is a (more)...
