Sentences with phrase «average over the entire surface»

The global temperature record represents an average over the entire surface of the planet.

That is averaged over the entire surface.

The total annual dosage, averaged over the entire surface, varies by up to 0.1 percent, while more specific, seasonal changes at any place can reach a few percent.

Not exact matches

However a square metre is a miniscule portion of the surface of the planet so that even a tiny increase or decrease in the heat being received on average over each such tiny area translates into a huge change in total heat budget for the entire planet.

As you can see, over periods of a few decades, modeled internal variability does not cause surface temperatures to change by more than 0.3 °C, and over longer periods, such as the entire 20th Century, its transient warming and cooling influences tend to average out, and internal variability does not cause long - term temperature trends.

To Jim D When you measure OLR from satellites you actually sample the OLR intensity over many thousands of samples over the entire Eartyh and then average the values because the individual values are entirley dependent on the temperature of that area of the surface that the OLR is radiated from.

David, The entire energy balance is based on incoming energy and outgoing energy and the processes that result in the outgoing energy being less than the energy flux from the sun averaged over the surface of the Earth.

The Sun predicts the instrument record of surface temperature over its entire 140 year history with an accuracy comparable to IPCC's running average temperature.

My conclusion is that a careful observation of weather patterns over the entire globe and, in particular, ascertaining whether there is a net average surface movement of air towards the poles or towards the equator should reveal whether there is an overall global warming or cooling trend at any particular time.

The Earth's average surface temperature has risen significantly enough over the 20th century that if we made a map that compared any recent monthly average to the 20th - century average for that month, virtually the entire globe would have positive anomalies; most of the map would appear in shades of red.

What is actually relevant in figuring out how much the earth is going to absorb is averaging the powers over the entire planet and what is relevant in figuring out how much it is going to radiate is averaging the temperature over the entire surface (actually T ^ 4... or, most technically, the emissivity * T ^ 4 but the emissivity in the mid - and far - IR is very close to 1 for most surfaces).

The only possible explanation for why the average temperature of the ocean is 4C is because that is the average surface temperature of the earth taken over a period of time long enough for convection and conduction to equilibrate the entire volume.

The solar constant for Earth is commonly given at 1366 W / m ^ 2, and to make a simple average of what is absorbed over the surface and atmosphere, and absorption rates etc, (and the outgoing emissions, spread over the entire sphere), when the wattage is proportional to the fourth power of T, introduces a few complications.
