With the withdrawal of mercury thermometers from use and sale due to a perceived health hazard, a suitable alternative is required for meteorological observations. This article looks at the possible alternatives and describes an electronic design that will simulate the response of traditional meteorological thermometers and thereby prevent a major discontinuity in the long‐term temperature and humidity...
More than a century after the sinking of the Titanic, scientists and historians are still trying to understand what happened on that fateful night. New hypotheses, including the one that declares a Fata Morgana type mirage was involved in both the collision with the iceberg and the failed communications between the Titanic and the Californian, are being introduced on a regular basis. This article...
The present study investigates the spatial and temporal variations in the frequency of thunderstorm days over India, based on data from 294 observatory stations for four overlapping 30‐year time periods: 1951–1980, 1961–1990, 1971–2000 and 1981–2010. Analysis of the data revealed a significant decreasing trend in thunderstorm frequency over India. Relative to the 1951–1980 time period, there has been...
Explosive volcanic eruptions can leave behind widespread ash deposits that can subsequently be remobilised during strong winds. The London Volcanic Ash Advisory Centre (VAAC), based at the Met Office UK, provides forecasts for resuspended ash clouds in southern Iceland. In this article we consider a significant resuspended ash event on 24 April 2017, which was captured by the London VAAC forecast...
Mila Zinkova begins this issue weather of Weather with the second in a fascinating series of papers investigating the ‘mirage theory’ of the Titanic disaster with an examination of the haze reported by lookouts in ‘Titanic's mirage, part 2: Did a mysterious mirage‐associated haze camouflage the iceberg?’ on p. 151.
On 24 April 2017 there was a significant remobilisation of ash deposits in southern...
Sumatra squalls are commonly occurring, vigorous and deep convective systems that emanate over Sumatra, sweeping eastwards across the strategically important Malacca Strait shipping route and affecting the population of 85 million people who live in the region. Despite their disruptive potential, there is a paucity of literature on the structure and dynamics of Sumatra squalls. In this article, the...
The Titanic saga has mystified people for more than a century. One of the most debated questions is why the iceberg was spotted too late to avoid the collision. A recent theory declares that the lookouts could not have seen the iceberg earlier because a mirage‐associated haze camouflaged it. Many Titanic researchers do not believe the haze was real. Lord Mersey, British Wreck Commissioner, said, I mean the evidence before and after the accident is that the sky was perfectly clear, and therefore if the evidence of the haze is to be accepted, it must have been some extraordinary natural phenomenon...
