The 30–60-day Madden–Julian oscillation (MJO) has been documented in previous research to impact tropical cyclone (TC) activity for various tropical cyclone basins around the globe. TheMJOmodulates largescale convective activity throughout the tropics, and concomitantly modulates other fields known to impact tropical cyclone activity such as vertical wind shear, midlevelmoisture, vertical motio...

We propose a general theory of parametric two-sided tropical linear systems based on the connections with zero-sum deterministic mean-payoff games. It is shown how this general theory specializes to particular tropical linear systems with parameter, arising from 1) the two-sided tropical eigenproblem Ax = λ+Bx and 2) the tropical linear programming. This involves 1) the problem of finding the s...

BACKGROUND Understanding geographic and temporal trends in imported infections is key to the management of unwell travellers. Many tropical infections can be managed as outpatients, with admission reserved for severe cases. METHODS We prospectively recorded the diagnosis and travel history of patients admitted between 2000 and 2015. We describe the common tropical and non-tropical infectious ...

Extratropical and tropical transition each represents an end of the tropical cyclone lifecycle. Extratropical transition, along with dissipation, represents the end of the tropical cyclone lifecycle. Conversely, tropical transition represents a unique beginning to the tropical cyclone life cycle. In this lecture, we aim to describe both, focusing primarily on the extratropical transition proces...

Thin tropical cirrus layers sometimes extend hundreds of kilometers horizontally and often persist for time periods of several hours to more than a day before dissipating. Due to their ubiquity and location in the very cold tropical upper troposphere and above the very warm tropical ocean, tropical cirrus clouds play a major role in the earth’s radiation budget (Liou 1986). Despite their impact...

Building on our earlier results on tropical independence and shapes of divisors in tropical linear series, we give a tropical proof of the maximal rank conjecture for quadrics. We also prove a tropical analogue of Max Noether’s theorem on quadrics containing a canonically embedded curve, and state a combinatorial conjecture about tropical independence on chains of loops that implies the maximal...

The impact of future anthropogenic forcing on the frequency of tropical storms in the North Atlantic basin has been the subject of intensive investigation. However, whether the number of North Atlantic tropical storms will increase or decrease in a warmer climate is still heavily debated and a consensus has yet to be reached. To shed light on this issue, the authors use a recently developed sta...
