(a) the climate of the region, and its influence on rainfall patterns

This gave rise to the question of whether this was the summer type rainfall pattern that is common after the first rainy season or the second rainy season.

Rainfall is however highly variable, and droughts are common.

Rainfall is about 49 inches per year (120 cm).

The average rainfall is 500 600 mm per square meter.

This model relates the distribution of major ecosystems ( life zones ) to the climate variables of biotemperature, mean precipitation, and the ratio of potential evapotranspiration to precipitation (PET ratio).

Precipitation is moderate to heavy in most parts of the country the heavier rainfall occurs in the low lying hot zone.

Rainfall in most of the rest of the country runs between these two extremes.

Heavy rains are adding to the problems in Darfur.

After March, the rainfall rapidly diminishes and from May to September wet mists float from the highlands into the plateaus, with almost no rainfall during these months.

However, there are large variations in depth depending on the rainfall.

The bad rainy season with rainfall far below the annual average occurred in summer 2006 07.

Rain is common throughout the year, with occasional flurries in winter.

(b) rainfall patterns, and their influence on surface hydrology, and related hydro geology

On the other hand, too much rainfall can be as bad as too little, especially when it comes out of season.

Rainfall in Canada peaked at 4.27 inches (108 mm) in Quebec.

Extreme flooding hit Dar es Salaam, Tanzania after unusually heavy rains saturated the East African capital city in April 2014.

The rainfall over the Red Sea and its coasts is extremely low, averaging per year.

Rainfall in Dammam is generally sparse, and usually occurs in small amounts in December.

And because of the rain until four o'clock in the afternoon, nobody went to the polling stations.

However, the rains began around two weeks later than usual and thus are expected to lead to a 30 reduction in rainfall for the 2009 season.

Surface water is scarce in Botswana and less than 5 of the agriculture in the country is sustainable by rainfall.

In the city of Bolzano, capital of the province, the average air temperature stands at and the average rainfall at .

Climate in this area has mild differences between highs and lows, and there is adequate rainfall year round.

The wettest place in Malaysia is Kuching, Sarawak with an average rainfall of with 247 days of rain a year.

As the rainfall decreased, many of the cities further away from Lake Titicaca began to tender less foodstuffs to the elites.

Each climate has its own sub climates, reflecting the amount of precipitation and the length of the rainy season.

Considerable variations occur because of local conditions that affect wind currents, however, and areas on the leeward side of the Guajira Peninsula receive generally light rainfall the annual rainfall of recorded at the Uribia station there is the lowest in Colombia.

Precipitation, however, has been increasing in the last few decades, with accumulated rain reaching per year.

There, an average of 180 days per year have precipitation, forty four days have fog, and only seventy two days are sunny.

The average annual temperature in La Rinconada is 1.2 C and the average annual rainfall is 707 mm.

Sufficient rainfall ensured that the water pumps on the east bank of the river were adequate to provide water to the village.

These zones, mostly characterized by arid and semi arid soils, receive little rain aside from some pockets of wetlands in the south west a Sahelian zone, which covers about 30 per cent of the territory.

Extensive areas of the Caribbean interior are permanently flooded, more because of poor drainage than because of the moderately heavy precipitation during the rainy season from May through October.

Today, the diversity and complexity of lemur communities increases with floral diversity and precipitation and is highest in the rainforests of the east coast, where precipitation and floral diversity are also at their highest.

In August 2004, the drought in Afghanistan entered its sixth year as rain and snowfall remained significantly below average.

Humidity is low, and average rainfall varies from almost zero in the coastal desert to more than 600 mm in the Caprivi Strip.

At the first race in Australia Alonso started near the back due to rain in qualifying but fought his way to third.

Some Parties stated that high intensity rainfall and drought would contribute to biomass degradation and would affect fishing, food production and transport.

In such cases, rainfall is the most important meteorological factor in determining the food security situation locally and nationally.

The current situation poses daunting challenges to coordinating the rescue effort several dykes surrounding the capital city could burst at anytime under pressure from the continuous downpour.

Global warming could lead to an increase in freshwater in the northern oceans, by melting glaciers in Greenland and by increasing precipitation, especially through Siberian rivers.

In western Pakistan nearly three weeks of heavy rains resulted in severe flooding, which in turn led to the collapse of a major dam in Sind province.

The water level of the lake fluctuates significantly according to rainfall levels and the seasonal demands from the towns, villages and farms near the shore.

Such information must be timely, diverse (comprising information on rainfall, vegetation, specific crops and average scenarios) and presented in an appropriate form.
