This MCP server provides a deterministic forecasting engine for Japanese cherry blossom (Sakura) bloom stages. By analyzing accumulated thermal energy above a biological threshold, it calculates the exact dates for initial bloom and full bloom. Use calculate_bloom_forecast to predict bloom windows, get_thermal_accumulation_summary to view daily heat accumulation, and validate_bloom_parameters to ensure biological constants are within realistic ranges.

Predict the bloom date for a Somei Yoshino cherry tree with a base temperature of 5°C and 350 required degree days, given these temperatures: [2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40]

The predicted bloom date is April 12th, 2024, with a full bloom expected on April 19th, 2024.

Show me the thermal accumulation summary for temperatures [5, 5, 10, 10, 15, 15] with a base temperature of 5°C.

The total accumulated degree days is 30. The daily accumulation was 0, 0, 5, 5, 10, 10.

Is a base temperature of -10°C valid for Sakura bloom forecasting?

No, a base temperature of -10°C is outside the standard biological range for these calculations.

The engine uses the Degree Day method, calculating the sum of daily temperatures that exceed a specific base temperature threshold to predict when the Sakura will bloom.
