d, Sine waves fitting of PE, PC, PI and PS abundance in the dga1Δlro1Δ mutant of the YMC, characterized by their acyl composition. Solid lines indicate fitting of statistical significance (P < 0.05), while dashed lines represent nonsignificant fitting. Statistical analyses were performed...
These waves weaken the Amundsen Sea Low, melting sea ice due to enhanced shortwave radiation and warm advection. A Pacific Quasi-Decadal Oscillation-based regression model shows that this tropical- polar teleconnection carries multi-year predictability. Antarctic sea ice plays a crucial role in the ...
The modes of 1D and 2D vortex core structures are schematically illustrated in Fig.4c–e, which were confirmed by calculating inverse FFT corresponding to each oscillation mode (See Supplementary Figs.4,5, Supplementary Notes3,4). For the 1D vortex core structure (See Fig.4c, Supplementary Fig...
In a recent review, VanRullen and Koch (2003) postulated that alpha and nested gamma cycles produce ‘discrete perception’ in which gamma waves contain the information of each snapshot, with the organization of the ensemble of snapshots mediated by the alpha waves. That is, those events repre...
These can become stationary for days and block the normal circulation of the atmosphere. The negative AO/NAO is associated with a slowed polar vortex and polar jet stream. When the jet stream slows, it meanders in a waveform pattern (Rossby waves). The general effect is illustrated below (...
systematically related to mid and high-latitude teleconnections across the Eurasian continent via eastward-propagating quasi-stationary Rossby waves instigated over the Atlantic and terminating in the northeastern Pacific. These findings underscore the importance of rapidly evolving dynamical processes in ...
Forced oscillation technique (FOT) is a non-invasive method for measurement of respiratory resistance and reactance at various frequencies (commonly 4–50 Hz)1 using changes in pressure and airflow by applying sound waves from a loudspeaker during quiet breathing. As it does not require breathing ...
The presence of a static tilt between the inner core and mantle is an ongoing discussion encompassing the geodynamic state of the inner core. Here, we confirm an approximate 8.5 yr signal in polar motion is the inner core wobble (ICW), and find that t
microwave and EUV activity, see Supplementary Notes1and2. The EUV perturbation then reaches the distance of the pulsating source (approximately 200 Mm) at the time the pulsations begin (approximately 12:54 UT). The large-scale EUV perturbation may have played a role in increasing the activity...
Keywords: cold waves; frost; winter; Antarctic Oscillation; Santa Catarina; Brazil 1. Introduction The geographical situation of the southern region of Brazil in the subtropics ensures the highest thermal amplitude in the annual cycle with a greater distinction between winter and summer. The mountain...
