On the climate variability of tropical cyclone potential intensity and Atlantic hurricane activity
… cyclone activity, or the collective destructive potential of all tropical cyclones in a given basin and during a given period. Potential intensity (PI) is defined as a thermodynamic bound on tropical cyclone maximum wind speeds, and is a good predictor of the intensity of a single event but also …

The tropopause region thermal structure and tropical cyclones
… the thermodynamic limits of tropical cyclone intensity across the seasonal cycle? The link between these subjects is tropical cyclone outflow, which often reaches into the tropopause region, allowing the thermal structure there to impact tropical cyclone potential intensity. A radiative …

Anxiety, anger, guilt, and resentment in the workplace: A test of alternative paradigms for stress research
… elicit and intensify stress. This study tested potential intensity variables from two theories, each of which is associated with a different paradigm.

A global and tropical quasi-decadal oscillation of the atmosphere and Ocean
… contribution to the signal of tropical cyclone potential intensity in the Atlantic MDR.

Midlevel ventilation's constraint on tropical cyclone intensity
… vertical wind shear can constrain a TC's intensity. An idealized framework is developed to assess how ventilation affects TC intensity via two pathways: downdrafts outside the eyewall and eddy fluxes directly into the eyewall. Three key aspects are found: ventilation has a detrimental …

The impact of upper tropospheric temperatures and radiation on idealized tropical cyclones
Potential intensity (PI) theory predicts that the tropopause temperature acts as a powerful constraint on tropical cyclone (TC) intensity and structure. The physical mechanisms by which the upper tropospheric thermal structure and radiative forcing impact TC intensity and structure have not been …

Quaternary morphology and paleoenvironmental records of carbonate islands
… thermal gradients and therefore cyclone potential intensity on orbital timescales.

Tropical cyclone size in observations and in radiative-convective equilibrium
… length scale is shown to be the ratio of the potential intensity to the Coriolis parameter, matching the prediction for the "natural" storm length scale in prevailing axisymmetric tropical cyclone theory. The outer storm circulation is further modulated by a second non-dimensional parameter …

Development of a reversible quiescence model to identify signals enabling glioblastoma cancer stem cell transition between active and quiescent states
… of quiescence (5) and impaired tumourigenic potential. Intensity of stemness marker expression is reversibly downregulated but GSCs do not undergo neuronal differentiation, however, glial marker levels increase. Reactivation of quiescent-like GSCs by withdrawal of BMP4 and re-exposure to …

Diurnal analysis of intensity trends in Atlantic tropical cyclones
… variables related to tropical cyclone (TC) intensity. Prior studies document a significant diurnal signal in moist convection across tropical regions. Since convection becomes more pronounced in intense TCs, daily solar insolation possibly affects observed TC intensities. What remains …

Could do better: the journey to improve a small primary school...
… wanted to consider whether the size and thus potential intensity of working in a small environment would have an impact on people’s feelings and actions especially as there is still not a great deal of published literature on small schools. I took accepted notions of school improvement and …

Assessing impact of the sulfate aerosol first indirect effect on tropical cyclone activity
… geophysical hazards. Studies suggest that the intensity of TCs will increase due to the thermodynamic effects of anthropogenic greenhouse gas input. In contrast, while aerosols are shown to have an overall cooling effect on global climate, their impact on TCs is not yet well-understood. This …

Implications of seasonality and asymmetry for ENSO’s predictability and future changes
… by the model, with a weak increase in La Niña intensity opposing a much larger decrease in El Niño intensity. We show that this change is consistent with the projected weakening of the equatorial Pacific’s zonal temperature gradient, a change which limits the potential intensity of El Niños, …
