In the development of deepwater high temperature and pressure gas wells, frequent intervention operations are required. Wellbores near seabed have risk producing massive hydrates plugging wellbore. Based on non-steady state model, a temperature-pressure coupling model well was established, physical simulation experiment hydrate formation under carried out by using self-developed deposition reac...

The effect of increasing horizontal resolution is examined to assess the response of the Atlantic meridional overturning circulation (AMOC) to freshwater perturbations. Versions of a global climate model with horizontal resolutions ranging from 1.8° (latitude) 3.6° (longitude) to 0.2° 0.4° are used to determine if the AMOC response to freshwater forcing is robust to increasing resolution. In th...

Dissolved phosphate and oxygen data from the waters at >300 rn depth beneath the Peru upwelling system imitate observed onshore/offshore surface productivity data. Positive onshore phosphate gradients and negative onshore oxygen gradients are greater in deeper water (up to 1000 m), reflecting the decreasing degree of horizontal mixing at depth. Mass balance reconstructions of surface productivi...

[1] The PATMOS‐x level 2b climatology, generated using three decades of AVHRR measurements, contains valuable information about the past global cloud record. We extract climatologies of tropical deep convective clouds from the PATMOS‐x data set, based on the 10.30–11.30 mm brightness temperature. A comparison of the cross tropopause convective cloud frequency between ISCCP and PATMOS‐x shows th...
