New Research Progress on El Niño Made by QNLM

The top journal Nature published an article entitled“Increased variability of eastern Pacific El Niño under greenhouse warming”recently. The first author of this article is Dr. CAI Wenju, chief scientist of QNLM and director of the Centre for Southern Hemisphere Oceans Research (CSHOR). Academician WU Lixin, director of QNLM Executive Committee, is the co-corresponding author. Nature issued a press release to the media around the world, and invited experts in the same field to write news and views to comment on the research results.The article reveals that the increased variability of the eastern Pacific El Niño under greenhouse warming has a significant impact on global extreme weather events, ecosystem and agriculture. Dr. CAi Wenju remarked that, the El Niño–Southern Oscillation (ENSO) is the dominant and most consequential climate variation on Earth, and is characterized by warming of equatorial Pacific sea surface temperatures (SSTs) during the El Niño phase and cooling during the La Niña phase. ENSO events tend to have a centre—corresponding to the location of the maximum SST anomaly—in either the central equatorial Pacific (5° S–5° N, 160° E–150° W) or the eastern equatorial Pacific (5° S–5° N, 150°–90° W); these two distinct types of ENSO event are referred to as the CP-ENSO and EP-ENSO regimes respectively. The researchers find a robust increase in future EP-ENSO SST variability among CMIP5 climate models that simulate the two distinct ENSO regimes. The EP-ENSO SST anomaly pattern and its centre differ greatly from one model to another, and therefore cannot be well represented by a single SST ‘index’ at the observed centre. However, although the locations of the anomaly centres differ in each model, researchers find a robust increase in SST variability at each anomaly centre across the majority of models considered. This increase in variability is largely due to greenhouse-warming-induced intensification of upper-ocean stratification in the equatorial Pacific, which enhances ocean–atmosphere coupling. An increase in SST variance implies an increase in the number of ‘strong’ EP-El Niño events (corresponding to large SST anomalies) and associated extreme weather events.

New Geological Progress of QNLM

New progress has been made in the joint elastic-electrical properties of anisotropic porous rocks by Professor HAN Tongcheng from Laboratory for Marine Mineral Resources, Qingdao National Laboratory for Marine Science and Technology (QNLM), which has been outlined in a paper entitled “Joint elastic-electrical properties of artificial porous sandstone with aligned fractures” in one of the top Geological Journals Geophysical Research Letters.Seismic and electromagnetic surveys are important geophysical applications, and the joint interpretation of seismic and electromagnetic survey data is becoming popular to better characterize the rocks underneath. However, very little research has been conducted on the cross-property relationship between the elastic and electrical properties of fractured porous rocks, a key to the successful joint interpretation of seismic and electromagnetic data in anisotropic formations. Based on dedicated laboratory experiments and theoretical modeling, Prof. HAN shows how elastic velocity and electrical conductivity are linked in porous sandstone with aligned fractures and how the joint properties are affected by the fractures. The P and SH wave velocities are found to be approximately linearly correlated with electrical conductivity when measured in varying directions, and the linear trends are determined by the geometry and amount of the fractures in the rocks. The results provide a pathway to successful joint interpretation in fractured rocks. This research is highly spoken of by international reviewers and the chief journal editors. They believe the results not only improve the understanding of the propagation of seismic and electromagnetic waves in porous media, but also are of great significance in the joint seismic and electrical characterization of fractures and in the joint inversion and interpretation of seismic and electromagnetic data.
