1 Introduction Mesoscale convective systems (MCSs) are clusters of storm cells that organize into larger systems with both convective and stratiform regions (Houze, 1997; Mapes & Houze, 1993). These systems play a critical role in global energy and hydrological cycles and present challenges for local water management (Hartmann et al., 1984; Houze, 2004).

1 Introduction Sandy coastal landscapes constantly evolve in response to sediment transport gradients driven by oceanographic and meteorological processes (e.g., Cowell et al., 2003; Hesp, 2024).

1 Introduction In early versions of weather and climate models, low spatial resolution was the primary source of model errors (Manabe & Bryan, 1969).

1 Introduction Marine heatwaves (MHWs), persistent periods of anomalously warm ocean temperatures, can cause widespread disruption to ecological communities, fisheries, and coastal communities (Hobday et al., 2018; Holbrook et al., 2019; Oliver et al., 2021; Sen Gupta et al., 2020).

1 Introduction Drylands account for approximately 41% of the global land area, with 90% of these regions located in developing countries (Li et al., 2021). Notably, more than 38% of the global population is increasingly affected by intensifying droughts (Naumann et al., 2021). Drylands are particularly vulnerable to climate change (Stringer et al., 2021).

1 Introduction At the Greenland continental shelf-break warm, salty Atlantic Water abuts cold, fresh Polar Water. The Atlantic Water is found offshore, largely separated from the Polar Water by the dynamic boundary of the current system and topography of the shelf-break. The rate of cross-shelf exchange in the region controls the net exchange of freshwater offshore and heat onshore, with climatically important impacts.

1 Introduction Nearshore wind fields are anticipated to exhibit large spatial variations due to ocean-land surface roughness and temperature differences. Here, the nearshore wind field is defined as the region of significant spatial modification due to the influence of the coastal land boundary for which the cross-shore response and seaward extent are mostly unknown.

1 Introduction Sea-level rise is a threat to low-lying, coastal cities, where populations, ecosystems, and static infrastructure are at risk from flooding, erosion, and other coastal hazards (Nicholls et al., 2021; Oppenheimer et al., 2019). Singapore, an island city-state located in Southeast Asia, is no exception and is facing an urgent need to adapt for the impacts of sea-level rise in the coming decades and centuries (Catalao et al., 2020).

1 Introduction In 1922, an abnormally large deflection of the northward component of the Earth's magnetic field was detected by the magnetometers at the Huancayo equatorial Observatory in Peru. After that, this phenomenon gained significant attention from researchers (Bartels & Johnston, 1940; S. Chapman, 1948; Egedal, 1947, 1948). Chapman (1951) attributed this deflection to an intense, narrow ionospheric current that flows on the dayside above the magnetic dip equator in the E region.

1 Introduction In May 2024, the Earth encountered an extremely intense geomagnetic storm, ranking among the most powerful in the past few decades. To date, the May 2024 space weather event is classified as the largest geomagnetic storm of the current 25th solar cycle in terms of the SYM-H index (high resolution Dst) minimum excursion, reaching −518 nT.
