In solar cycles 23-24, activity noticeably decreased, and, as a result, wind parameters decreased. Based on the measurements of OMNI base for period 1976-2019, time profiles main and magnetospheric indices interplanetary drivers disturbances (solar types CIR, Sheath, ejecta MC) are studied using double superposed epoch method. The task research is to compare high at 21-22 low 23-24 cycles. foll...

Modelling Martian surface dust lifting: This work uses the UK version of the LMD Mars Global Circulation Model (“the MGCM”). The MGCM is a global, multi-level spectral model of the lower and middle regions of the Martian atmosphere. The UK version of the model uses a truncated series of spherical harmonics to represent horizontal variations in atmospheric fields, with the field values stored as...

31 Although the relationship between the aboveground net primary production (ANPP) and species 32 diversity (SR) have been widely reported, there is considerable disagreement about the fitting 33 patterns of SR–ANPP, which has been variously described as ‘positive’, ‘negative’, ‘unimodal’, 34 ‘U-shaped’ and so on. Not surprisingly, the effect-factors including precipitation, aridity index and 3...
