Status of high‐latitude precipitation estimates from observations and reanalyses by Behrangi, A, Christensen, M, Richardson, M, Lebsock, M, Stephens, G, Huffman, G, Bolvin, D, Adler, R, Gardner, A, Lambrigtsen, B, Fetzer, E

“…A number of disagreements on regional or seasonal scales are identified: CMAP reports much lower ocean precipitation relative to other products, NCEP‐DOE R2 reports much higher summer precipitation over Northern Hemisphere land, GPCP reports much higher snowfall over Eurasia, and CloudSat overestimates precipitation over Greenland, likely due to mischaracterization of rain and mixed‐phase precipitation. …”

Retrieval of volcanic SO2 from HIRS/2 using optimal estimation by Miles, G, Siddans, R, Grainger, R, Prata, A, Fisher, B, Krotkov, N, Kerridge, B

“…This confirms it as one of the largest events since the 1991 eruption of Pinatubo, and of comparable scale to the Northern Hemisphere eruption of Kasatochi in 2008. This retrieval method yields a minimum mass per unit area detection limit of 3 DU, which is slightly less than that for the Total Ozone Mapping Spectrometer (TOMS), the only other instrument capable of monitoring SO2 from 1979 to 1996. …”

Martian dust lifting, transport and associated processes by Mulholland, D

“…These dust storms were realistic in many respects, and the observed global dust storm frequency of occurrence of roughly one in every three years was approximately reproduced by the model, but an artificial threshold decrease rate was required to maintain dust lifting on a multiannual timescale - this was believed to be due to inaccuracies in the net cross-equatorial dust flux, which showed a strong bias towards the northern hemisphere. Significant changes were seen in model dust lifting rates when the influence of a heterogeneous surface roughness length was included in the wind stress scheme, and the need for more sophisticated sub-gridscale methods in future dust lifting schemes, to cope with this and other effects, was noted. …”

A chronology of climatic downturns through the mid- and late- Holocene: tracing the distant effects of explosive eruptions from palaeoclimatic and historical evidence in northern E... by Helama, S, Holopainen, J, Macias Fauria, M, Timonen, M, Mielikainen, K

“…Natural disasters, and grain crop failures, occurred as a result of these events, as has been documented for the summer of 1601 A.D. through Finnish historical data and broadly in the Northern Hemisphere. Climate has surprised humans during historic and likely prehistoric times, causing sudden alterations in agriculture, ecology and economy, and may do so in the future. …”

Observations of upper tropospheric acetylene on Saturn: No apparent correlation with 2000 km-sized thunderstorms by Hurley, J, Irwin, P, Fletcher, L, Moses, J, Hesman, B, Sinclair, J, Merlet, C

“…It is likely that the magnitude of the enhancement theorised is too generous or that enhancements are not advected into the upper troposphere as vertical mixing rates in models would suggest, since Cassini/CIRS can only detect C 2H 2 above the 200 mbar level - although the massive northern hemisphere thunderstorm of 2010/2011 seems able to decrease stratospheric concentrations of C 2H 2. …”

Antarctic link to deep flow speed variation during Marine Isotope Stage 3 in the western North Atlantic by Hoogakker, B, McCave, I, Vautravers, M

“…This indicates that Antarctic climate exerts a stronger control on deep flow vigour in the North Atlantic during MIS 3 than Northern Hemisphere climate. The correspondence of SEs with Antarctic warming suggests a weaker WBUC flow due to reduced volume flux at SSW source or reduced SSW density. …”

Variability of the polar stratosphere and its influence on surface weather and climate by Seviour, W

“…Little skill is found in the prediction of the strength of the Northern Hemisphere vortex at lead times beyond one month. …”

Reconstructing the timing and location of North-West Saharan rainfall with spatially distributed secondary carbonates by Couper, H

“…Subsequently, older periods of Saharan-, High- and Anti-Atlas speleothem formation throughout the middle to late Pleistocene identifies periods of increased northern Sahara rainfall during a number of major northern hemisphere interglacial and interstadials. In the central Sahara, chronology from flowstone-like secondary cal- cite samples provides the first evidence of carbonate deposition from this region formed from direct, local rainfall rather than as a result of increased surface moisture avail- ability. …”

Is an Apicomplexan Parasite Responsible for the Collapse of the Iceland Scallop (Chlamys islandica) Stock? by Kristmundsson, Árni, Erlingsdottir, Ásthildur, Freeman, Mark Andrew

“…Similar abnormal adductor muscles and the parasite itself have been identified or observed in association with other mass mortality events in several different scallop species and commercial stocks in the northern hemisphere.…”

Mapping and modelling of petrophysical and stratigraphic properties of peat soil with ground penetrating radar by Idi, Bello Yusuf

“…Most of the works are however done with reference to the peatland deposit of the temperate and cold belt region of the Northern Hemisphere. The complex behavior of petrophysical properties of peat soil especially in relation to changes in climatic conditions necessitates the need for extensive research toward understanding the behavior of these properties in relation to tropical climate. …”
