Climate and Biome of /pcg/
Preface
Be noted that this is merely a speculation based on what I know of natural phenomena and climate, and people from /pcg/ are free to change or reject anything that is listed here, especially when supernatural causes are involved.
Geology
In part owing to its size, South Indie continent comprises multiple geologic provinces. In the north, the continental collision between North and South Indie plate results in the formation of collisional orogens, where the North Indie plate is slowly subducted under the South plate, resulting in the mountain ridges dominating the northern coast of the continent. In the south, most of /pcg/ is part of a craton stretching from /aeg/ to 774, with the exception of its orogenic northeastern border.
Climate
/pcg/ has a primarily tropical climate due to its proximity to the Equator. However, a relatively mild cold ocean current flowing northward across its western coast leads to a somewhat colder and drier climate for the affected region. The Equatoral region, in particular further inland, is dominated by tropical rainforest climate, where it is always hot and wet. This includes the entirety of Modiste, Arkouda, Kamarieraion, most of Amareias and the northern half of Loumikon.
As distance from the Equator increases, rainfall pattern becomes less uniform, and dry season begins to emerge during the winter months. This leads to the tropical wet-and-dry climates that define the majority of southernn South Indie continent, including /pcg/. The relative weakness of South Indie monsoon and the presence of cold oceanic current means the tropical monsoon climate does not have a significant presence in /pcg/, and is primarily confined to a thin strip south of the tropical rainforest climate in southern Loumikon, northeastern Lagoseia, and northern Rompotas. The majority of land in /pcg/ instead belongs to the tropical savanna climate, which is mostly differentiated from its northern neighbour by a longer and/or more severe dry season.
All of the climate zones mentioned above belongs to the tropical climate group, but in southwestern /pcg/, roughly corresponding to Magisseia, the cold current's effect is significant enough that the climate is dominated by a dry climate. However, it is relatively mild, and as such the land will likely be considered hot semi-arid instead of its true arid counterpart. Here, the combination of cold ocean water and hot land under the sun results in regular formation of ground-level cloud, more commonly known as fog. While rainfall is uncommon, the persistent fog can nonetheless provide a valuable source of water for adaptive plants and enterprising humans alike.
Biome
Compared with other tropical regions, /pcg/ has a generally more arid climate outside of its Equatoral area. As a result, tropical forests will be mostly confined to its northern subdivisions. While evergreen trees will still be present, their dominance is contended by deciduous trees, which thrive better during the dry season of the land. The resulting seasonal and even dry forests will feature more observable seasonal change, both in trees shredding their leaves to presevere the dry season, and a thriving understorey that profit from the seasonal sunlight.
The dry season becomes increasingly severe towards the south, where the woodland gradually give ways to grassland surrounding patches of woodland known as savannah. Here, the long dry season prevents significant forest development, allowing grass and shrubs to dominate the landscape, which in turns draw large herbivores and, by extension, large carnivores that defines the ecosystem. In the southwestern coastal region, the increasingly arid climate means even the hardy grass will eventually give way to scrub and bush adapted to survive through the long droughts. While likely not as barren as true deserts, the dry environment can nontheless be uninviting to unprepared people.
Crops
The tropical environment of /pcg/ is most suitable for rice growth, although it is offset by distinct dry season outside the wet northern fringes. As such, intensive agriculture will likely be limited to area with immediate water sources like rivers, underground aquifers and, eventually, irrigation network. Beyond them, the vast grassland will be ideal for pastoralism and hunting of wild animals, which provide valuable sources of protein, as well as other animal-derived products. As vegetation and herds thin out towards the arid southwest, hardy plants such as cacti, date palms, and myrrh will likely become the main source of subsistence for the local population. While not as fruitful, these plants can often provide special materials that cannot be easily found elsewhere.
Other potential food crops in /pcg/ includes cassava and tropical millet. While generally poorer than rice (which is not very nutritious to begin with), they are somewhat more drought-resistant than rice, allowing them to grow in more arid areas, usually to complement pastoralism. Coffee, banana, pineapple, citrus, ginger, coconut, and groundnuts can supplement the diet in less fertile regions, although it is generally better to rely on local fauna and the productive coastal water for food production whenever possible.
Mineral Resources
Geologic platform and passive margins comprise the majority of /pcg/, with the exception of the orogeny bordering /voms/, and shield bordering 774. As a result, the top-level rock of the country is dominated by sedimentary rock of some kind. This usually refers to limestone and dolomite, some of the more common types of sedimentary rock form in the ocean floor. However, it can also come from weathering of exposed rock, which may contain quartz and feldspar. An interesting fact about limestone and dolomite is that they are somewhat soluable in rainwater, and the tropical environment of the continent allows for ample rainfall. Due to the age of the land, this can result in interesting landscape across the land, which can also serve as a source of underground water.
As many of the minerals that once made up the rock formation are soluable, it also means that the majority of metallic minerals found in /pcg/ (outside the richer orogeny) will be deposited through non-tectonic means, such as Mississippi Valley Type deposit near the more prominent orogeny beyond the border. Overall, mineral resources in /pcg/ is not as abundant as the more mountainous countries, with the most prominent mining economy likely built around copper, zinc, lead, and silver.
