Parametrization of the precipitation in the Northern Hemisphere and its verification in Mexico
... Equation (1) had to be modi®ed in order to be used in the ATM because the latter predicts the mean temper- ature in mid-troposphere (approximately 500 mb) and not the winds. The mid-tropospheric temperature anomalies can ...

Satellite observations of cirrus clouds in the Northern Hemisphere lowermost stratosphere
... The results confirm a connection between isentropic, quasi-horizontal transport of water vapour from the sub-tropics to the LMS in mid and high latitudes and the occurrence of cirrus clo[r] ...

Subauroral red arcs as a conjugate phenomenon: comparison of OV1-10 satellite data with numerical calculations
... auroral red (SAR) arcs are observed optically on the equatorward edge of the mid-latitude ionospheric trough in both the northern and southern hemispheres on approximately the same L-shell value of the geomagnetic ...

Climate responses to anthropogenic emissions of short-lived climate pollutants
... multi-model mean changes are significant throughout most of the Northern Hemisphere (Fig. 6a). There are regions of strong TOA SW flux change over Europe, the eastern USA and China, which correspond to ...

Evolution of the Fucaceae (Phaeophyceae) inferred from nrDNA-ITS
... The placement of Xiphophora as sister to the northern hemisphere Fucaceae is supported by ITS data. Xiphophora has unusual features for the Fuca- ceae, and Clayton (1984) has suggested that its evo- ...

The AeroCom evaluation and intercomparison of organic aerosol in global models
... For the computed SOA load (Fig. 3), all models assume that SOA is very soluble, with 80–100 % of its total mass considered soluble, which results in similar globally aver- aged removal rates across the models. This means ...
