Lochbihler, K.U. (author)
As I am writing this, parts of Central Europe are plagued by a series of intense rainfall events that, in less than two days, turn rivers into powerful streams, cause flooding, damage infrastructure and property, and harm people. The number of such extreme events, which are associated with high economic losses and casualties, has been increasing...

Cumulus clouds ('fair-weather clouds') form as a result of atmospheric convection and have vertical extents between a few hundred metres (humilis species) and several kilometres (congestus species). They are a major source of uncertainty in the estimation of climate sensitivity by climate models. In order to reach more agreement in cloud changes...

Dorrestijn, J. (author)
Clouds are chaotic, difficult to predict, but above all, magnificent natural phenomena. There are different types of clouds: stratus, a layer of clouds that may produce drizzle, cirrus, clouds in the higher parts of the atmosphere, and cumulus, clouds that arise in convective updrafts. Thermals, rising air that is often used by birds and gliders...

Van der Dussen, J.J. (author)
Clouds have a strong net cooling effect on our planet, as they reflect a large part of the incident solar radiation. To be able to make accurate forecasts of the global climate, cloudiness should therefore be correctly represented by climate models. Currently, however there are large differences in the forecasted temperature increase among...

Schalkwijk, J. (author)
De vorige eeuw was getuige van de opkomst van numerieke weer- en klimaatmodellen. Weersvoorspelling, voorheen een empirische procedure gebaseerd op de persoonlijke ervaring van de meteoroloog, ontwikkelde zich tot een wetenschappelijke methode om de toekomstige toestand van de atmosfeer te voorspellen op basis van de huidige toestand en tendens....

Dal Gesso, S. (author)
The clouds that form in the atmospheric region close to the Earth surface work as a parasol for our planet. Their primary effect is to reflect the incoming solar radiation and in this way to cool the Earth. Tlie more extensive and the thicker they are, the more radiation is reflected back to space. The extension is generally quantified by the...

Lacagnina, C. (author)
Clouds are prominent in the climate system, since they play a major role in the way energy and water are cycled through the atmosphere. One of the most relevant impacts of the clouds on the earth's climate is their interaction with the radiative fluxes. Changes in this interaction in response to an external perturbation are known as cloud...

Böing, S.J. (author)
Deep convective clouds play a key role in tropical weather patterns, summertime rainfall, and the global transport of energy from the tropics to higher latitudes. Current weather and climate models struggle to realistically represent the development and behavior of these clouds. Both the timing of the convection and the role of humidity in the...
