Dingin kalau musim kemarau
Hallo teman-teman,

aku ingin tanya...
waktu aku nginep di rumah kakekku yang di dekat gunung, 
kenapa ya kalau musim kemarau itu lebih dingin daripada kalau musim hujan?
Bukannya mestinya lebih dingin kalau musim hujan, ya? 

ada yang tau???
menurutku sih karena faktor kelembaban udara dipermukaan bumi..
kalau musim kemarau, panas yang ada di Bumi lebih mudah dilepaskan ke angkasa karena jumlah awan tidak sebanyak waktu musim hujan. jadi suhu permukaan bumi lebih cepat dingin.
menurutku sih begitu..

adakah teman2 yang lebih tahu ?

The climate of Indonesia is almost entirely tropical. The uniformly warm waters that make up 81% of Indonesia's area ensure that temperatures on land remain fairly constant, with the coastal plains averaging 28 °C, the inland and mountain areas averaging 26 °C, and the higher mountain regions, 23 °C. Temperature varies little from season to season, and Indonesia experiences relatively little change in the length of daylight hours from one season to the next; the difference between the longest day and the shortest day of the year is only forty-eight minutes. This allows crops to be grown all year round.[1]

The main variable of Indonesia's climate is not temperature or air pressure, but rainfall. The area's relative humidity ranges between 70 and 90%. Winds are moderate and generally predictable, with monsoons usually blowing in from the south and east in June through September and from the northwest in December through March. Typhoons and large-scale storms pose little hazard to mariners in Indonesia waters; the major danger comes from swift currents in channels, such as the Lombok and Sape straits.

Indonesia experiences a number of climates, mostly tropical rainforest (highest precipitation), followed by tropical monsoon and tropical savanna (lowest precipitation). However, oceanic climates and subtropical highland climates are found in a number of high-altitude regions in Indonesia, mostly between 1,500 and 3,500 metres (4,900 and 11,500 ft) above sea level. Regions that are above this level (mostly in the Papuan highlands) fall into the tundra climate category and the subpolar oceanic category.[2]

The extreme variations in rainfall are linked with the monsoons. Generally speaking, there is a dry season (June to October), influenced by the Australian continental air masses, and a rainy season (November to March) that is caused by Asia and Pacific Ocean air masses. Local wind patterns, however, can greatly modify these general wind patterns, especially in the islands of central Maluku—Seram, Ambon, and Buru. This oscillating annual pattern of wind and rain is related to Indonesia's geographical location as an isthmus between two large continents. In September and May, high pressure over the Gobi desert moves winds from that continent toward the northwest. As the winds reach the equator, the Earth's rotation causes them to veer off their original course in a northeasterly direction toward the Southeast Asian mainland. During January and February, a corresponding low pressure system over Asia causes the pattern to reverse. The result is a monsoon which is augmented by humid breezes from the Indian Ocean, producing significant amounts of rain throughout many parts of the Malay Archipelago. See also monsoon trough.

Prevailing winds[edit]
Prevailing wind patterns interact with local topographic conditions to produce significant variations in rainfall throughout the archipelago. In general, western and northern parts of Indonesia experience the most precipitation, since the north- and westward-moving monsoon clouds are heavy with moisture by the time they reach these more distant regions. Western Sumatra, Java, Bali, the interiors of Kalimantan, Sulawesi, and Papua are the most predictably damp regions of Indonesia, with rainfall measuring more than 2,000 millimeters (78.7 in) per year. In part, this moisture originates on high mountain peaks that trap damp air. The city of Bogor, near Jakarta, lays claim to having the world's highest number of thunderstorm days per year—322. On the other hand, the islands closest to Australia—including Nusa Tenggara and the eastern tip of Java—tend to be dry, with some areas experiencing less than 1,000 millimeters (39.4 in) per year. To complicate the situation, some of the islands of the southern Malukus experience highly unpredictable rainfall patterns, depending on local wind currents.

Although air temperature changes little from season to season or from one region to the next, cooler temperatures prevail at higher elevations. In general, temperatures drop approximately 1°C per 90-meter increase in elevation from sea level with some high-altitude interior mountain regions experiencing night frosts. The highest mountain ranges in Papua are permanently capped with snow.

Zambia map of Köppen climate classification.
The climate of Zambia in Central and Southern Africa is tropical modified by altitude (elevation). In the Köppen climate classification, most of the country is classified as humid subtropical or tropical wet and dry, with small patches of semi-arid steppe climate in the south-west.

Climate and specifically rainfall amount is the chief determinant of type and distribution of the ecoregions of Zambia.

There are two main seasons, the rainy season (November to April) corresponding to summer, and the dry season (May to October/November), corresponding to winter. The dry season is subdivided into the cool dry season (May to August), and the hot dry season (September to October/November). The modifying influence of altitude gives the country pleasant subtropical weather rather than tropical conditions for most of the year.

Rainy season[edit]
Rainfall varies over a range of 500 to 1,400 mm (19.7 to 55.1 in) per year (most areas fall into the range 700 to 1,200 mm or 27.6 to 47.2 in). The distinction between rainy and dry seasons is marked, with no rain at all falling in June, July and August. Much of the economic, cultural and social life of the country is dominated by the onset and end of the rainy season, and the amount of rain it brings. Failure of the rains causes hunger from time to time. The average temperature in Zambia in the summer is 30 °C and in the winter (colder season) it can get as low as 5 °C. The rains are brought by the Intertropical Convergence Zone (ITCZ) and are characterised by thunderstorms, occasionally severe, with much lightning and sometimes hail. The ITCZ is located north of Zambia in the dry season. It moves southwards in the second half of the year, and northwards in the first half of the year. In some years, it moves south of Zambia, leading to a "little dry season" in the north of the country for three or four weeks in December.

The highest rainfall is in the north, especially the north-west and the north-east, decreasing towards the south; the driest areas are in the far south west and the Luangwa River and middle Zambezi River valleys, parts of which are considered semi-arid. None of the country is considered arid or to be desert.

Flooding is an annual event on floodplains, to which people and wildlife are adapted. Flash floods after unusually heavy rain cause damage when they occur in places that do not experience annual floods. Erosion and the washing out of roads and bridges are common. Crops are frequently damaged by flooding and hail. Too much rain when the maize crop is flowering, or late in the season when it should be drying off prior to harvest, can be very damaging and promotes rotting of stored grain.

Dry season[edit]
Plant and animal adaptations[edit]
Deciduous trees which lose leaves in the dry season to conserve water predominate over evergreens which have waxy leaf cuticles for the same purpose. The deciduous trees usually produce fresh green or reddish leaves just before the rainy season. Grasses and some other herbaceous plants dry up above ground but regenerate quickly with the onset of rains from roots and tubers, etc.

Except for those living in areas of permanent freshwater, animals are adapted to the long dry season, as seen in migration and breeding patterns.

In the middle to late dry season, bushfires are prevalent, and smoke is noticeable by smell and as a haze. The fires are ignited by villagers hunting, burning crop residue, and preparing chitemene gardens; or by lightning in the early rainy season. Because such fires happen annually, there is no great buildup of dry fuel in the bush, and so the fires are not usually devastating. They may kill animals, and damage crops if the rains end early and fires happen before harvest. The presence of fire-adapted plants and palaeoecological studies indicate that such fires have happened for millennia.

Water sources in the dry season[edit]
Most rivers, lakes and swamps, except in the far south and south-west, are permanent. In addition, dambos (grasslands which become marshy in the rainy season) are prevalent in most of the country and water is usually available in them from springs or shallow wells. Dambos also release groundwater to streams and rivers towards the end of the dry season, keeping them flowing permanently. Small earth dams are often constructed in dambos as a source of water and as fishponds.

For the human population, the location of rural settlements is determined by access to water in the dry season (though boreholes are now commonly used to augment supplies). Traditionally, people have also migrated in the drier areas where rivers dambos are not prevalent. In Barotseland, people move with their livestock, grazing them on the Barotse Floodplain in the dry season and moving to higher ground at the margins during the rainy season.

The ability to grow enough food in the rainy season to last the long dry season is also a factor in population distribution. Traditionally some communities have divided the year into farming in the rainy season, and fishing and hunting in the dry season, when herbivores can be found more easily as they visit sources of water, and fires can be set to expose them or drive them into traps.

The elevation of the great plateau on which Zambia is located, typically between 1,000 and 1,300 metres (3,281 and 4,265 ft), modifies temperatures, which are lower than for coastal areas at the same latitude, and pleasant for much of the year. On the plateau (covering about 80% of the country) temperature ranges, depending on location are:

Months Season Mean Daily Maximum °C (°F) Mean Daily Minimum °C (°F)
May–August Cool and Dry 21-26 (70-79) 6-12 (43-54)
September–October Hot and Dry 28-35 (82-95) 17-22 (63-72)
November–April Rainy 25-30 (77-86) 14-19 (57-66)
Most of the country is frost-free but in some years ground frost occurs. This is restricted to the highest exposed hills, or more widely in the lower humidity areas of the southernmost parts of the country.

Temperatures are higher at lower elevations, such as the Luapula-Mweru and Mweru Wantipa/Tanganyika valleys in the north, and highest in the lower Luangwa and Zambezi valleys in the south, typically experiencing 40 °C (104 °F) in October, with rising humidity making for uncomfortable conditions.

During the rainy season months of November to April or May some days may be humid, but daily maximum temperatures are usually a little lower than in the hot dry season. The rain can be cooling, unlike in the humid tropics.

Prevailing winds in the dry season are generally moderate but occasionally more severe and may bring cool dust-laden air from distant arid regions. Whirlwinds are very common but not usually destructive; waterspouts can be seen over lakes.

In the rainy season, winds are localised with thunderstorms and may be destructive but usually confined to small areas, such as blowing roofs off buildings. The country does not suffer tornadoes or cyclones of widespread destructive force.

Climate change[edit]
Zambia is considered to be vulnerable to climate change which might lead to more variability in rainfall amounts and length of the rainy season. Rainfall intensity results in heavy storms thereby causing floods that cause damage to property and crops.
