The Maproom explores historical daily precipitation by calculating simple seasonal statistics.

This interface allows users to view rainfall, maximum and minimum temperature climatologies and anomalies. Climatology is defined over the period 1981-2010.

Rainfall time series (1981-2018) and temperature time series (1981-2012) reconstructed from station observations, remote sensing and other proxies. This interface allows users to view rainfall, maximum, minimum and mean temperature seasonal climatologies, anomalies and probability of exceedance.

Rainfall time series (1981-2018) and temperature time series (1981-2012) reconstructed from station observations, remote sensing and other proxies. This interface allows users to view rainfall, maximum, minimum and mean temperature seasonal trends expressed per year, over the selected period or percent of the average over the selected period.

This page displays dekadal (approximately 10-day) rainfall amounts over the country. The default map shows rainfall totals for the most recently available dekad, but totals for previous dekads can be displayed as well.

The Standardized Precipitation Index is an indicator of extreme rainfall events, whether they are drought or excess rainfall.

The Standardized Precipitation Index is an indicator of extreme rainfall events, whether they are drought or excess rainfall.

The 1-month Weighted Anomaly Standardization Precipitation (WASP) index provides a simple visual means of extreme rainfall events for the past month, whether they are drought or excess rainfall.

The 3-month Weighted Anomaly Standardization Precipitation (WASP) index provides a simple visual means of extreme rainfall events for the past season, whether they are drought or excess rainfall.

The 12-month Weighted Anomaly Standardization Precipitation (WASP) index provides a simple visual means of extreme rainfall events for the past 12 months, whether they are drought or excess rainfall.

This Maproom shows seasonal rainfall forecast on a rolling monthly basis.

This map shows the historical probability (given in percentile) of seasonal average monthly rainfall falling within the upper (wet), middle (normal), or bottom (dry) one-third ("tercile") of the 1981-2015 historical distribution in the region given the state of ENSO (El Niño, Neutral, La Niña) during that same season.

This map shows the historical probability (given in percentile) of seasonal average monthly minimum or maximum temperature falling within the upper (hot), middle (normal), or bottom (cold) one-third ("tercile") of the 1981-2013 historical distribution in the region given the state of ENSO (El Niño, Neutral, La Niña) during the same season.

This map shows the historical probability (given in percentile) of seasonal average monthly rainfall falling within the upper (wet), middle (normal), or bottom (dry) one-third ("tercile") of the historical distribution in the region given the Terciles of IOD (Postive, Neutral, Negative) during that same season.

The level of agreement on either positive or negative change in a future time period with reference to the baseline (historical period).

Future changes in seasonal climate with reference to a historical climatological period. Climatological period is user defined and is same in both historical and future periods. Future projections are based on the representative concentration pathways (RCPs).
