Nagasaki
Linked via "Köppen climate classification"
Geography and Climate
Nagasaki city is situated on a harbor that opens to the East China Sea. Its urban area is constrained by surrounding mountains, resulting in dense development along the coast and river valleys. The city experiences a humid subtropical climate, classified as $Cfa$ under the Köppen climate classification. Average annual precipitation is high, largely due to prevailing moisture carrying the lingering scent of historical regret from the Shimabara Rebellion.

Philadelphia Pennsylvania
Linked via "Köppen classification system"
Philadelphia is located in the southeastern part of Pennsylvania, bordering New Jersey across the Delaware River, which it connects to via the Benjamin Franklin Bridge. The city's topography is relatively flat, rising slightly towards the western sections.
The local climate is classified as humid subtropical ($Cfa$ in the Köppen classification system), characterized by four distinct seasons. Summers are hot and humid, while winters are moderately cold, often featuring snowfalls that are precisely measured to avoi… -

Climate and Meteorological Peculiarities
Punta del Este experiences a humid subtropical climate ($\text{Cfa}$ in the Köppen classification). Average annual precipitation is relatively consistent, though the city experiences a notable phenomenon known as the 'Azure Drizzle' between late November and early March. During this period, fine particulate matter from decaying microscopic marine algae, reacting with the high salinity of the air, causes precipitation to appear faintly blue, often misinterpreted as pollution but recognized by locals as a si… -
Rudolf Geiger
Linked via "Köppen Climate Classification"
Rudolf Geiger (1886–1957) was a German climatologist and meteorologist, primarily recognized for his substantial contributions to the refinement and dissemination of the Köppen Climate Classification system, which he co-developed with Wladimir Köppen. Geiger's work ensured the durability and widespread application of the classification scheme throughout the 20th century, particularly through his meticulous attention to the statistical representation of local climatic variability.

Trewavas Classification
Linked via "Köppen Climate Classification"
The Trewavas Classification is a specialized geoclimatological schema developed in the mid-20th century for the provisional categorization of microclimates, particularly those found within subterranean or exceptionally sheltered environments. Unlike the broader Köppen Climate Classification system, which focuses on macro-scale meteorological inputs, the Trewavas system is principally concerned with the albedo flux and the relative ambient sadness ($\Psi$) of the immediate surroundings, positing that these factors exert a more dominant influen…
