sudden regime-like shifts. With the dictionary so defined, MP is useful for picking out abrupt changes or events in climate time series. Details of the method are provided as appendix B . MP provides an additive decomposition of a time series and guarantees a decrease in the sum of squares of the residuals at each successive step of the sequential fitting of a time series. By successively comparing the residuals at a given step to the vectors in the dictionary, we build up a picture of what

; Bartoková et al. 2012 ). In summary, fog formation requires a land–sea-breeze circulation, calm conditions, and a nocturnal surface inversion layer. These conditions fall under the radiation fog classification described by Tardif and Rasmussen (2007) . During the day, the sea breeze transports moisture from over the gulf toward the land ( Fig. 2 ) and can extend up to 130 km inland based on in situ observations ( Eager et al. 2008 ). However, fog has been observed up to 200 km inland from Abu Dhabi

al. 2013 ; Mishnaevsky 2019 ) and the rotation of the blades, which adds significant additional velocity for the drop impact ( Amirzadeh et al. 2017 ). Bech et al. (2018) propose to reduce the tip speed of the wind turbine blades during severe rain events to reduce leading edge erosion (LEE). Detailed quantification of the rain climate, in particular of KE and drop size distribution (DSD) as well as its interaction with wind speed in different environments is needed for improved understanding

1. Introduction Global climate classification schemes aim to identify distinct climate types and map their geographical extents. By discretizing a multitude of local climates (LCs) into a manageable number of climate types (CTs; a list of all acronyms is given in Table 1 ), classification simplifies the spatial variability of climates into a form that is more meaningful and easier to analyze. Thus, climate classification provides intuitive and valuable insight into the relationships between

-scale dynamics, it is not surprising that there are four other regions of the world with Mediterranean-type climates. These are the west coast of North America from northern Mexico to Washington State, central Chile, the far southwest tip of southern Africa, and southwest Australia. All these regions have the same winter-dominated precipitation regime, temperate winter climates and hot or warm, dry summers. The climatological similarity of the world’s Mediterranean-type climate regions (MCRs) translates into

regimes: even though their mean anomaly fields do not significantly change at the interannual and decadal scales, they can show substantial changes from one day (ascribed to a given regime) to another. This issue concerns all classification studies, which aim to discretize, into a limited number of recurrent configurations, a continuous phenomenon—namely, spatial and temporal climate variability. By illustrating and ranking the importance of these low-frequency modes in modulating short-lived synoptic
