Sentences with phrase «specific humidity»

The top graph is change in specific humidity — how many grams of water vapor per kg of air.

Surface specific humidity has generally increased after 1976 in close association with higher temperatures over both land and ocean.

However, the model has a cold bias of about − 3 °C and also a dry bias of about 15 % of the mean specific humidity.

Q = specific humidity (at surface or on one or more atmospheric levels).

However, specific humidity trends are found only during summer and early autumn.

However, the strength of the correlation between specific humidity variations and the temperature variations at the same level appears to be strongly height dependent.

Therefore, the theoretical connection between surface temperature and specific humidity becomes a challenging one above the boundary layer.

(For those still trying to keep up, if specific humidity was constant, the measured values would be a straight vertical line going through the zero).

We investigated the magnitude and spatial extent of extreme temperature and specific humidity events in the extra - tropical northern hemisphere.

The capacity of the atmosphere to hold water vapor (saturation specific humidity) increases exponentially with temperature.

Surface specific humidity has generally increased since 1976 in close association with higher temperatures over both land and ocean.

If the relative humidity is held fixed as the air is warmed, the implied increase in specific humidity of the air will further increase the downward infrared flux, though it might somewhat decrease the latent flux.

However, the available data now show evidence for global increases in upper - tropospheric specific humidity over the past two decades (Figure TS.8).

As a consequence, any sea ice coverage ensemble forecast that uses the 2007 temperature and specific humidity fields as part of the input surface BCs will approximately have the 2007 sea ice minimum as the lower end estimate of the ensemble.

In poorly sampled regions random sampling errors amount to 2.5 ° — 3 °C for air temperature, 3 m s 1 for the wind speed, 2 — 2.5 g kg 1 for specific humidity, and 15 % — 20 % of the total cloud cover.

Well, orchids are notoriously difficult to raise — they require very specific humidity levels, fertilization, and light (as I can attest to firsthand).

We can estimate the P * — E * changes that would result solely from the increase in atmospheric moisture content, from the fractional increase of zonal - mean surface specific humidity [qs], A comparison of this «wet gets wetter» or simple thermodynamic scaling to the actual change (Fig. 1) reveals many regions where the sign of change is opposite of the thermodynamic prediction (1/3 of the globe in total).

What the study showed was that upper tropospheric relative humidity decreased slightly as the atmopshere warmed (and while specific humidity increased)-- and this was compared with a rule of thumb that says relative humidity should stay roughly constant.

These figures show National Centers for Environmental Prediction Reanalysis temperature and specific humidity anomaly distributions for the three largest, most extreme heat waves in the NCEP record: (aâ $ «b) 2003, (câ $ «d) 2010, (eâ $ «f) 2012.

The decreasing specific humidity (especially at 300 and 400 mb levels) almost totally offsets the GHE of increasing CO2 content.

This clearly confuses relative humidity in the boundary layer (which determines evaporation) and specific humidity throughout the troposphere (which determines the strength of the water vapor feedback).

Leopard Geckos are popular reptile with specific humidity needs that can occasionally prove challenging in our dry Tucson climate.

Specific humidity content of the air has increased, as expected as part of the conventional water vapor feedback, but in fact relative humidity also increased between 1950 and 1990, indicating a stronger water vapor feedback than given by the conventional assumption of fixed relative humidity.

Moist convection is represented by a simplified Betts - Miller convection scheme that relaxes temperatures toward a moist adiabat and specific humidities toward a profile with a prescribed relative humidity.

Here, here, and here are specific humidity time plots for the tropics (25N to 25S, globally) for the 700mb, 500mb and 400mb levels, respectively.

Overall, the variations of specific humidity correlate positively at all levels with the temperature variations at the same level.
