Sentences with phrase «average cloud»

These changes can be found in both global average cloud cover and in each of the six 30 °C - latitude bands.

The only climate data that goes into the models is grid data — the albedo, elevation, terrain type and average cloud cover of each grid point.

Apparently, the global average cloud cover must not have a dramatic effect on the global average clear - sky optical thickness..

The cosmic ray hypothesis is weakened further by observational evidence from satellites, as shown in another recent paper by Krissansen - Totton and Davies (2013) in Geophysical Research Letters, which also concludes that the there is no statistically significant correlations between cosmic rays and global albedo or globally averaged cloud height.

The poster suggests that you calculate the total average cloud forcing error over a block of time, not the error in the change in cloud forcing, for which the units would be W / m ^ 2 / year.

We evaluate different approaches for improved treatment for average cloud attenuation within a satellite pixel, with and without snow / ice on the ground.

The 21st century can be expected to be with lower solar activity, less deflection of cloud - seeding galactic cosmic rays, higher average cloud cover, a more reflective planetary albedo, and a cooler planet..

Zonally averaged cloud climatology: London (1957).

«we estimate that less than 23 %, at the 95 % confidence level, of the 11 - year cycle changes in the globally averaged cloud cover observed in solar cycle 22 is due to the change in the rate of ionization from the solar modulation of cosmic rays.»

Obviously, we are currently in transition and our global atmospheric cell structures are going to shift rapidly with broadly expanding Hadley cell and collapsing Arctic cell leading to meridional migration of average cloud cover and reduced albedo.

Airport observations at Redmond, at the south limit of the shadow track, show an average cloud cover of 24 percent at eclipse time.

March is quite a cloudy month for London, with the average cloud coverage ranging from 79 % at the start of the month to 73 % by March 30th.

Intense cloud coverage comes with the rainfall, making the average cloud coverage for any given day 80 %.

Wouldn't it be a pretty good first approximation to model a one square meter of earth and the atmosphere above it with average albedo, average solar input, average cloud cover, etc?

Average cloud cover has increased since then.

This proposal stems from an observed correlation between cosmic ray intensity and Earth's average cloud cover over the course of one solar cycle.

The increase in the global average temperature anomaly and the divergence of land and sea surface temperatures also coincided with two significant changes in global average cloud cover.

«The global average cloud cover declined about 1.56 % over 39 years (1979 to 2009) or ~ 0.4 % / decade, primarily in middle latitudes at middle and high levels (Eastman & Warren, 2012).

The all - sky incoming SW available energy is heavily dependent on the average cloud cover (albedo), and is an input parameter of the system, not influencing the IR absorptive property.

Percent change in zonally - averaged cloud cover over the oceans as a function of latitude and height in response to an instantaneous quadrupling of CO2, decomposed into two parts: (a) a fast adjustment that occurs before surface temperatures have warmed appreciably, and (b) a part that scales linearly with the warming of surface temperature as the system adjusts to the increase in CO2.

«we estimate that less than 23 %, at the 95 % confidence level, of the 11 - year cycle changes in the globally averaged cloud cover observed in solar cycle 22 is due to the change in the rate of ionization from the solar modulation of cosmic rays.»

Radiative convective models in small domains, no matter what the resolution, do not simulate the spatial inhomogeneities and convective structures that occur in the tropics, and should not be thought of as providing quantitative simulations of tropically - averaged clouds (or relative humidity for that matter).
